Indexed: 2026-05-21

[00:00:00]Hello student friends, are you ready?

[00:00:02]Science Capsule Series has been started.

[00:00:04]Three videos in the Science Capsule series Uploaded in the last lecture I was current.

[00:00:08]By covering electricity problems Given in this lecture or in this series In the fourth part, we will learn about mole molarity.

[00:00:15]The concept of molecules and their related Attempt to complete the numericals Okay, let's see again, moles or But before learning molarity, we need to know two things.

[00:00:23]One should have basic conceptual knowledge.

[00:00:25]One would be the atomic number and the other would be the atomic mass.

[00:00:28]The number is fine, just remember those two things.

[00:00:30]Give the atomic number and atomic mass number to you.

[00:00:32]Even if everyone knows, just once Let's brush up on everything here, Tomik number.

[00:00:38]What is represented by what?

[00:00:40]Everyone knows that it's just a simple thing.

[00:00:42]First lecture of this series Even though I said these things in Let me revise the number of protons once.

[00:00:49]The number of electrons in a atom is given by the atomic number.

[00:00:51]What do you mean by that element or The proton or electron that the atom possesses Understanding numbers is the most important thing.

[00:00:58]Where are protons present?

[00:01:01]Protons are present in the center.

[00:01:04]If any charge is present, it is positive.

[00:01:05]The charge will be the second number of protons.

[00:01:08]Electron neutrality is always equal to Or the element is electrically neutral.

[00:01:15]They are because they are close to the element.

[00:01:17]The number of electrons present is The number of protons is the same as the number of electrons.

[00:01:21]Denoted by simple test Vision is the most important thing, first of all.

[00:01:27]What are the 30 elements of the periodic table?

[00:01:29]Their atomic number given in Symbols are things you know.

[00:01:34]It's okay, it's just that.

[00:01:36]Simply remember the atomic number of an The element here is carbon for example.

[00:01:40]You have considered the atomic number six.

[00:01:43]What does that mean for carbon?

[00:01:46]What is the number of protons? Six What will be the number of electrons? Six What is the atomic number of helium?

[00:01:51]The atomic number of helium is two, which means What exactly is the proton that helium has?

[00:01:56]Number two or helium How many electrons are there in two basic Let's keep things in mind and continue.

[00:02:02]Next, the second concept is atomic mass.

[00:02:05]Everyone knows that Tomick Mass is the Number of Protons Neutrons in Tum Ki A proton and a proton possessed by a atom Or the number of protons plus neutrons So who is going to be the atomic mass proton?

[00:02:18]Where are they present in the center of the atom?

[00:02:20]Where are neutrons present in the nucleus?

[00:02:22]Located in the center of the nucleus Proton atomic mass is present here.

[00:02:26]Written as proton plus neutron That is, who is the atomic mass or for this I had said one more word.

[00:02:31]Nucleons are called atomic masses simply Proton plus neutron, look here again.

[00:02:37]Even when I was telling you, you were telling me, Tom.

[00:02:39]It is electrically neutral but has a tomic The proton is a positively charged particle.

[00:02:45]Is the electron negatively charged?

[00:02:47]The particle is a neutron.

[00:02:49]No type of charge is the most important thing.

[00:02:52]Tomic mass denoted by measured in Daltons The units are OK for example sodium.

[00:02:58]Tomic mass Tomic mass of carbon So what is Proton Plus going to be?

[00:03:03]The number of neutrons, as I told you, It is said that the atomic number of the element is known.

[00:03:10]First 30 element atomic numbers needed You should know the commission.

[00:03:14]There is no guarantee that you will pass the exam.

[00:03:17]And the first 20 element atomic masses too You should know this by now.

[00:03:22]Based on atomic number and atomic mass The next concept will be yours.

[00:03:27]Molecular mass Now if we understand the mole If you want to take it, you need to know the molecular mass.

[00:03:33]Children, the elements should know.

[00:03:35]Atomic mass is the atomic mass of hydrogen.

[00:03:38]Carbon has an atomic mass of carbon or Hydrogen oxygen has an atomic mass but When elements are present in a fixed proportion They come together to form a compound.

[00:03:48]For a compound that does not have an atomic mass, Let us calculate the molecular mass.

[00:03:52]It would be necessary to apply the same concept here molecularly.

[00:03:55]Even if it's a fish, I'll give you a simple one.

[00:03:57]Let me explain, do you have the elements?

[00:04:00]What are the elements? What are elements made of?

[00:04:03]Since there are elements, these elements are combined.

[00:04:06]The element element has an atomic mass that is What you should know about fish Tomick Masses is already given that As you should know, when Elements in a fixed proportion They come together, I would say, in fixed proportions.

[00:04:20]They create compounds whenever they want.

[00:04:22]What does a compound have? Molecular mass.

[00:04:25]And this molecular This molecular mass is not part of the translation.

[00:04:28]Okay, you had to calculate.

[00:04:31]So now we can look at this molecular mass.

[00:04:33]Let's start here, see what molecular mass is.

[00:04:36]Representative of the caste of capital A. Representative Let's just write simple here again.

[00:04:42]Tomic Masses Together Key to Molecular Mass Deduction Why is there no scientific term, just simple?

[00:04:48]Element present in some compounds Here is the sum of the atomic masses that exist.

[00:04:53]Written as the sum of the masses of all the elements Present in the molecular compound now What molecule is H2? What compound is H2?

[00:05:05]That means you have a molecular atomic mass.

[00:05:07]Calculate or subtract the compound molecular mass from the equation.

[00:05:11]What does it mean to sum up all the dishes?

[00:05:14]The more elements are present in the mass The sum of the atomic masses of that element What does it mean to have molecular mass?

[00:05:22]Simply remember these things again.

[00:05:24]Here is an example of what they wrote: The structure shown in methane CH4 is rough I'm doing it.

[00:05:32]Now look here who is present in methane How much hydrogen is present in one carbon?

[00:05:36]Four hydrogens are present.

[00:05:37]When calculating, a simple calculation will do.

[00:05:40]One should have atomic information of carbon.

[00:05:43]How many would be 12 plus hydrogen?

[00:05:46]How many are four hydrogens and four hydrogens?

[00:05:49]How many will there be, Tom? If there is one, do it.

[00:05:52]Multiplication is one point 12 12 4 * 1 = 4. How much is it?

[00:05:56]12 + 4 = 16 so this is called methane What is the molecular mass of the compound?

[00:06:02]It's going to be 16 Daltons.

[00:06:05]Atomic mass of elements and compounds Molecular Mass Atomic masses of elements You should know at least 20 Note the atomic masses of the elements. Someone Very difficult element organ would have been given the same You were mentioned by Tomic Mass.

[00:06:21]There are 118 atomic masses of elements.

[00:06:25]This task should be okay, not again.

[00:06:27]Tell me, what is the second third in molecular mass?

[00:06:30]Nothing, baby, just simple atomic masses.

[00:06:32]What should be done is to add up.

[00:06:34]This stress is mentioned in the example here.

[00:06:37]Why are you giving us the price again?

[00:06:39]The concept of the name is the value of studying the concept.

[00:06:42]Molecular mass should be taken for molecular Atomic masses to calculate mass Information should be available if atomic mass information is available.

[00:06:50]If not, the molecular mass will not be calculated.

[00:06:52]If there is no molecular mass, then it is called mole.

[00:06:53]I don't understand the concept, everything is linked.

[00:06:56]Keep in mind, okay, a little further.

[00:06:58]Let's start with atomic number atomic mass I Taken in the first lecture of the series So I'll speed up a little.

[00:07:05]Let's continue things again.

[00:07:08]Here is a written example of an empirical formula.

[00:07:11]Things that have molecular formulas I'll tell you something here to help you understand.

[00:07:14]I tell you all to understand.

[00:07:15]The formula of glucose will be known as glucose.

[00:07:18]C6 HTO Si We call this glucose. What is this about glucose?

[00:07:23]Well done, kids, the molecular formula is glucose.

[00:07:26]Why is a molecule a type of molecule?

[00:07:28]The formula you use to represent Used to represent an element We know it by its molecular formula.

[00:07:35]I'm saying, but we need another formula.

[00:07:37]Empirical formulas need to be remembered.

[00:07:39]Empirical formula is simple.

[00:07:41]In mathematics, we draw simple lines.

[00:07:43]The smallest ratio is the same.

[00:07:46]Empirical Formula Key Molecular Formula with any digit or What happened to all of these if they were divided by numbers?

[00:07:54]I want to go to the right part for the example.

[00:07:57]Suppose C6 H2O6 is divided by six.

[00:08:01]What will happen if I do this? Divide by six here.

[00:08:05]Let's see how many H2 and O are there in 12?

[00:08:08]If it is, what happened to six CH2?

[00:08:12]The empirical formula of glucose became empirical.

[00:08:16]What is the formula?

[00:08:18]Molecular formula Molecular formula That is, to represent molecular What formula did you use?

[00:08:26]Representing the element This represents the number of elements.

[00:08:31]What if the six is ​​a vote for this six?

[00:08:34]What is the factor that you What will be created if divided?

[00:08:39]Empirical formula now you can use empirical What does Formula Six multiply?

[00:08:43]Do this and you will get the molecular formula.

[00:08:45]Divide the molecular formula into cine.

[00:08:47]What will you get by the empirical formula?

[00:08:49]The molar formula contains a simple ratio.

[00:08:52]Okay, I'll explain the rest to you.

[00:08:54]I have two concepts, one molecular formula.

[00:08:58]Second Empirical Formula Empirical Formula What is the representation of the simplest whole number ratio?

[00:09:05]Said to be the simplest hole number That means it's going to be one to the four of us.

[00:09:11]Simplest whole number ratio of res tum Present in Compound Present in Compound The present tense has a simple tense.

[00:09:20]It's okay to remember these things.

[00:09:23]Here's what the molecular formula does.

[00:09:26]Representative Actual Number of Tums Here The molecular formula gives you the actual number.

[00:09:31]We see that glucose contains carbon.

[00:09:33]How much is six hydrogen? How much is 12?

[00:09:35]How much is oxygen, six but empirical?

[00:09:37]What do you see in the formula?

[00:09:39]I meet to see the simplest whole number race.

[00:09:42]What is ratio in its simplest form?

[00:09:44]You may be able to see the formula here.

[00:09:46]Things to remember are molecular.

[00:09:48]Formula Here is a formula auction.

[00:09:50]Molecular formula equal to N in Empirical formula in the case of glucose What was N in the value of N?

[00:09:58]It's going to be six, remember simple.

[00:10:00]When will you be asked to write a molecular The formula will be asked as an empirical formula.

[00:10:04]But remember this formula.

[00:10:06]Molecular formula equals empirical Remember the formula Molecular formula Actual number of items present Empirical formula is the simplest way.

[00:10:17]These things to remember when it comes to numbers Look here again about glucose.

[00:10:23]What can we do here? Let's see how much carbon is there.

[00:10:27]One hydrogen, how many two oxygens, how many one Tarav Resh is simple, Resh is so basic.

[00:10:35]We had concepts, now we have actual ones.

[00:10:37]Should I start here or is the formula the same?

[00:10:40]Molecular formula of glucose See how you are represented here.

[00:10:44]A question was asked, now let's look at this question.

[00:10:46]What have you given to the commission so far?

[00:10:48]If you say an atomic number, atomic mass number.

[00:10:52]Molecular mass empirical formula is very basic.

[00:10:55]This is a concept, this is the concept of the Already Me series.

[00:10:58]In our first lecture in the forest The explanation was done in great detail, so We had turned on the speed a little, now we are really tired.

[00:11:04]A simple question was asked here.

[00:11:08]Percentage of Carbon in Glucose Percentage information is called percentage to everyone.

[00:11:13]What is going to happen in h? We are calculating.

[00:11:15]There are 100 carbons in glucose.

[00:11:18]How much is the percentage in glucose in Simple?

[00:11:21]Look, why did he get such questions?

[00:11:23]There is no such thing as a formula, simply how?

[00:11:25]Let me know what you think.

[00:11:28]Okay, let's do it first. What will you do?

[00:11:30]The first step would be the molecular structure of glucose.

[00:11:33]The formula to be written down is C6H2O2.

[00:11:37]Now calculate the molecular weight of glucose.

[00:11:39]Formula calculates the second stem We need to know the molecular mass now.

[00:11:44]We will see how to calculate molecular mass.

[00:11:46]What you want to do is sum the atomic masses of all Let's calculate the element.

[00:11:52]Write below how much carbon is six in one The atomic mass of carbon is 12, what is the atomic mass of hydrogen?

[00:11:58]There are 12 atomic masses of hydrogen.

[00:12:01]How many oxygen atoms are there and what is the atomic number of oxygen?

[00:12:04]How many months would it be? It would be 16. Okay, I'll color.

[00:12:07]I'll highlight it for you.

[00:12:09]How much of those things did you understand?

[00:12:10]If you want six, how much is the carbon?

[00:12:12]Why did you take six 12? Why did you take hydrogen 12?

[00:12:15]So how much oxygen is there in six carbons?

[00:12:18]What is the atomic mass of 12 hydrogen?

[00:12:20]What is the atomic mass of oxygen? 16 It's okay, but keep these things in mind Let me know if you need help here.

[00:12:28]Why is molecular formula important?

[00:12:30]Let's multiply it, how much will it be? 72 How much will 12 plus be? 96 cross checking Go and do your math, it will be great for me again.

[00:12:40]How much does it cost after dishing out all of this?

[00:12:42]It would have been 180 degrees, it's okay, it's simple.

[00:12:46]What do you do with the molecular mass of glucose?

[00:12:49]Calculated, children, you need glucose.

[00:12:51]Why didn't you ask for the molecular mass and not the percentage of Carbon in glucose, now look again, what is 180?

[00:12:58]Carbon plus hydrogen plus oxygen The sum of all atomic masses is 180.

[00:13:04]Look at this glucose carbon in this 180 here.

[00:13:07]I highlight with another color.

[00:13:10]You will notice that here is the full How much carbon is present in the scenario?

[00:13:16]72 is present Carbon 72 is in 180 What is the carbon contribution? 180 You will be asked how to calculate percentage.

[00:13:26]You will solve it in two ways.

[00:13:27]I will remember as much as I can about the percentage here.

[00:13:30]Calculates color change in 180 It takes a minute.

[00:13:37]It's simple, look how much carbon is in 180.

[00:13:40]If it is 72, then how much is it in 100?

[00:13:45]Calculations are simply done this way.

[00:13:48]Will zero zero be canceled?

[00:13:52]18 Ch 72 Kainar If 40%T Or Simply If This may seem difficult, but cross multiplication How much carbon is in 180? 72 is 100.

[00:14:03]How many X's will there be in the cross?

[00:14:05]What is Multiplication Cross Multiplication?

[00:14:07]It will be 72 times 100 divided by 180, okay.

[00:14:12]First, you do the cross multiplication step.

[00:14:14]Use or directly as if in 180 If 72 is 100, what is the percentage?

[00:14:19]Why highlight the upcoming 40 percent?

[00:14:22]To show you here that in 180 How much is carbon? If it is 72, then 72 in 180.

[00:14:27]So how many out of 100 will be the percentage?

[00:14:29]It's 40%, look, it's a simple question.

[00:14:32]You asked such a question.

[00:14:34]Molecular mass for the first time after asking The total molecular mass that will be calculated Some of the components that were asked in What is the contribution percentage?

[00:14:43]It's okay to ask what you're going to do.

[00:14:46]Remember the concept, continue now.

[00:14:50]Your topic starts in Kchul, Mol.

[00:14:52]The concept of the name simply means to remember There is no second or third thing to the amount of substance.

[00:14:58]The unit that makes the major is the fundamental unit.

[00:15:01]You should remember that there is value here.

[00:15:04]Written mole accounting unit chemistry We are using smart forms as a value.

[00:15:11]Kanting said the unit will be major.

[00:15:13]How many representative specific count of subs The present is the form of the value you have.

[00:15:19]Expressing unit of measurement for What does the amount of subs matter?

[00:15:26]Let's look at the amount of substance again.

[00:15:29]That is, what is the number equal to the number of Carbon Tums in Azctly 12 Gum of Poor Carbon Carbon 12 Carbonate Why Carbon We looked at the isotopes carbon 12 carbon 13 What is one mole of carbon 14?

[00:15:48]How many Tums are present in Pure Carbonate?

[00:15:52]What value would there be if there were so many tums?

[00:15:55]Now, if you have any units you want to use, If so, we are setting some standard.

[00:16:01]So is this standard in the case of moles?

[00:16:03]Standard says that a mole is exactly How many numbers are equal to what?

[00:16:11]of carbon tums ezctly int grams of per But which carbon is in carbon?

[00:16:21]The amount of Tums present in carbonate That's what it's going to be like now.

[00:16:26]If you feel a little confused, just Keep this in mind if you are asked to give a number in the exam.

[00:16:33]Carbon tums in ezctly Just remember that gum off carbon is just The second thing to remember is the number size.

[00:16:46]Ray Power is most important Should the value fit in the head?

[00:16:52]Said number one male contribution is one mole of Anything Consists of Key Concept of Value Honor those who gave their names to the scriptures We call them numbers to do so.

[00:17:04]This value is for you, but for the exam.

[00:17:06]It is important from a perspective and this is one Problem with the statement being correct?

[00:17:11]The commission has asked many times, but little We will continue with our concerns.

[00:17:18]Simple again, now a simple information.

[00:17:20]How many eggs are in a dozen?

[00:17:23]They said, "Now I don't have any."

[00:17:25]When you say substance one mole, you mean It should be remembered that one mole of X equals Two dozen eggs means how many 12 eggs?

[00:17:33]How much is a mole of eggs? 6.02 Ray Power X Pull Just Specific Coity But Universally, now look at the small things.

[00:17:45]We use moles to measure things.

[00:17:47]What is the significance of this entire slide?

[00:17:50]I will tell you the most important thing.

[00:17:52]I would give this formula a four star rating somewhere.

[00:17:55]Please star this formula somewhere.

[00:17:58]Take notes, children, you must remember.

[00:18:00]What is the formula for? Number of moles written here Here's how the number of moles is calculated.

[00:18:07]Do you know what M means?

[00:18:10]Given a mass of substance or In simple language, I say, "Given Mass."

[00:18:17]But what should the mass be in grams?

[00:18:20]It should be divided by M molecular mass.

[00:18:24]For this we need to know the molecular mass.

[00:18:26]If you want to calculate the desired value, You are given a number of moles equal to Mass in grams divided by molecular mass I will keep it simple, but I will tell you here.

[00:18:39]This formula is very simple to write once.

[00:18:41]The number of moles is very important.

[00:18:47]Equal to Given month You can write grams in brackets.

[00:18:57]Divided by Molecular Mass Now For this, molecular mass testing is done.

[00:19:03]Will you be given a compound whether you go or not?

[00:19:05]You need to calculate the molecular mass.

[00:19:07]It's okay, it's simple, I'll remember the number.

[00:19:10]Moles given mass divided by molecular mass Look here, on its basis, they I asked the question, look at me again.

[00:19:19]I will write you another formula.

[00:19:21]This is the first formula after the number of moles.

[00:19:23]Note down another formula, children.

[00:19:26]Number of molecules How to calculate the number of molecules Number of moles Number of Moles in Addro Number Number Value What was 6.02?

[00:19:45]Te Re Powert3 This is a formula but it is very important.

[00:19:49]Number of molecules to remember two Formula number of moles given mass in grams Divided by Mollicar second number off Remember the molecules here.

[00:20:00]Number of molecules will be asked in the exam.

[00:20:02]Give or ask for the number of ions.

[00:20:05]Or let's ask for the number of particles.

[00:20:08]Any number of molecules, number of ions Number of particles or number of atoms Even if something is asked in the exam, there is only one formula.

[00:20:16]It is important to remember the number of moles in Avgadah.

[00:20:19]What is the value of the number Avgad number 6.6.02?

[00:20:24]Ray Power 23rd Here is the point 6.

[00:20:32]These two formulas of power are very important.

[00:20:34]Look again, I will come to you further.

[00:20:36]It's like numericals make you understand things.

[00:20:39]I will tell you two things.

[00:20:41]Must have information, remember the number of The formula for moles number of molecules is Now look further, the commission asked very nicely.

[00:20:49]The question is, they asked.

[00:20:51]Maximum number of molecules present Below are four options given and asked Maximum of the four options given below Now, the number of molecules is a bit more.

[00:21:02]The background is the number of molecules.

[00:21:05]What is the formula written in Number of Moles?

[00:21:08]The value of the add number will change.

[00:21:11]Is this a constant value? 6.02 Ray Power 23 What number off is necessary for you?

[00:21:19]Moles if you want the number of molecules What information do you need first?

[00:21:24]Must have number of moles information The value you want is an integer number, then a constant.

[00:21:29]It will be, nothing will change, nothing will change.

[00:21:30]No, back to the question, let's look here now.

[00:21:33]Asked Maximum Number of Molecules Now After the Commission asked such questions, all four By calculating the molecules of the alternative I would like to see the first option calculated.

[00:21:43]We don't want to tick the answer, let's try now.

[00:21:47]See here for the commission to solve the tomic mass Hydrogen given, carbon given, oxygen given Iodine was given, now it seems like they will always give it.

[00:21:56]Why don't we have the first 20?

[00:21:59]Must know the atomic masses of the elements This is iodine, an element like iodine.

[00:22:04]If they don't know, they mention it.

[00:22:06]Let's try it first, see what happens 250 Gum of iodine crystal should be remembered here now.

[00:22:13]Give We see halogens fluorine chlorine bromine Iodine is called iodine, it is I2.

[00:22:19]Why don't you just buy one of these halogens?

[00:22:22]They are present in diatomic form.

[00:22:25]Table VIII Group No. 17 Halogens OK The first second is 22 grams of carbon.

[00:22:30]What is carbon dioxide?

[00:22:32]C2 gives us the basic molecular formula.

[00:22:36]Must know 45 Gum of F Gum of Water Water is what H2 and 10 Gum Off mean?

[00:22:42]Hydrogen gas What is in hydrogen gas?

[00:22:45]Will take H2, will take OK basic information We have written, now we will number each element.

[00:22:51]Let's calculate the off-mole, what do you want to see the number?

[00:22:53]Calculate the mass of a mole using the given mass formula.

[00:22:56]Remember how much Gin Mass was given first.

[00:22:59]I write 250 divided by I2 in molecular How much iodine is needed to calculate the mass? 127 Write 127 plus 127 here, it will be the first option.

[00:23:12]Let's give another option. What else?

[00:23:15]Given mass divided by formula, the number is given.

[00:23:19]Of moles Given month Divided by Molecular Mass Given mass divided by molecular mass OK What is the molecular mass of CO2?

[00:23:36]How do you calculate?

[00:23:38]Let's see here, CO2 is one carbon.

[00:23:41]Carbon is 12 plus oxygen, what is two?

[00:23:43]Option two oxygen th oxygen 16 how much What is 12 plus 32? 44 Look at this again, the test will give you molecular If the mass is not going to the heart, the children will calculate.

[00:23:54]How many is 44 divided by 22? 44 is okay, third here.

[00:23:58]I am writing the third option number 45 gum off.

[00:24:01]Water 45 is given Water eight H2 Water H2 Hydrogen is two hydrogens times oxygen.

[00:24:09]How many hydrogens are there, how many ox options are there?

[00:24:11]There is one option, 16. How much will two plus 16 be?

[00:24:15]What happened to 18? 18 is the molecular mass of water.

[00:24:19]There will be one and A here write 45 deed Option number three Option number What is the difference between four and hydrogen?

[00:24:30]What is the atomic mass of one hydrogen atom? One H2 That is, how many two divided by two is each?

[00:24:37]The alternative is to calculate the dam in the exam.

[00:24:39]It's necessary, okay, okay, then look here.

[00:24:41]What is going to happen if 250 is divided by 14 and This is two divided by 254. Suppose I am four less.

[00:24:51]What will happen if you do it? Almost 250 baht It will be almost one, but if you subtract four, it means What can I understand about Calculation Z? Na98 or Or something will come because suppose we subtract four.

[00:25:03]If there was one, I would have to come back again.

[00:25:06]Look how much a 22-two is going to cost.

[00:25:11]How many years does it take to get a big one? Look here.

[00:25:17]18th 54 If there is something more than three If the least participator is something more than three Even if it should come down, we will see.

[00:25:28]How much is Faded Buy coming in? 2.5 coming in?

[00:25:32]And B, five, how many will come? Five will come.

[00:25:35]Look at this, what did you calculate?

[00:25:38]2.50.5 And the number of moles calculated is Of mole asked why number of molecules Asked but the formula for the number of molecules Remember, this is the molecular number.

[00:25:51]Will the value of moles number change or not?

[00:25:55]This value is going to be constant, meaning The number of moles is higher.

[00:26:00]How will the molecules be at most?

[00:26:02]If so, then look at these four options.

[00:26:05]Who has the most number of moles here?

[00:26:08]Whose water is it, sorry, how much is hydrogen?

[00:26:12]The number of moles is five, so the number of But who has more molecules?

[00:26:16]Hydrogen will be option number four.

[00:26:20]One option will tell you a lot.

[00:26:22]Question: Number of molecules, please give your thoughts.

[00:26:25]Here, even if you ask the number of ions or Even if you ask for the number of Tom, children, The same method was used to think that you were a Give Tums Thought Molecules Thought Sem Formula Number of Moles in Adore Number Number How to calculate the number of moles if given Mass Divided by Molecular Mass Now It was necessary to calculate the molecular mass.

[00:26:46]Is CO2 given here or not? We are using CO2 here.

[00:26:49]44 is calculated, ok 44 How much water was calculated there 18 here Water is calculated, okay?

[00:26:59]Remember option number four answer Let's continue later.

[00:27:04]Look again at this type of question commission.

[00:27:06]Whatever questions you're trying to ask I am trying to make you understand.

[00:27:10]I will do some things before I do this.

[00:27:12]Will try to make you understand.

[00:27:13]Take a note somewhere, baby, that one Do you remember a little about the concept of value?

[00:27:19]What is a mole 6.02 Ray to Power 23 Ions Molecules tums Some of the molecules in a mole are noted here.

[00:27:31]How much is 6.02?

[00:27:34]Ray Power 23 or how many Tums in one mole?

[00:27:38]6.02 * 10 Rays to the power 23 Tums Or what will happen to the particles etc. All the second most cases that I have here now This is the first time I write things for you.

[00:27:50]Scenario remember the second I'm here See the article One Mole of Water How much is in one mole of water?

[00:28:00]The molecules will have 6.02 Z Ray Power.

[00:28:05]There will be molecules.

[00:28:08]Or how many ions are in one mole of water?

[00:28:11]There will be only one mole of ions per second.

[00:28:14]Water If you ask one mole of water, one mole of water.

[00:28:20]What is its mass? How much is it going to be? 18 Keep in mind that there will be a village or How else can you express seconds?

[00:28:28]You can find one mole in the number of molecules.

[00:28:31]Number of molecules or now suppose I Wrote One Mole Off C2 How many molecules are there in one mole of C2?

[00:28:42]That's all, that's all, how much is 6.02?

[00:28:45]Ray Powerth Molecular Now you make a dozen How many will you find in a dozen?

[00:28:52]You will meet, take one egg, how many will you meet?

[00:28:56]Will you meet a dozen, which means 12, as we have?

[00:28:59]In daily life or take one kilo of wheat How many will you get? One thousand grams will you get?

[00:29:03]Take a kilo of jowar and you will get a thousand grams.

[00:29:05]That's right, kids, you are a mole of water.

[00:29:08]Consider or one mole of CO2 Consider or any other ions Or consider a molecule as one mole.

[00:29:16]That is, the molecular number is equal to the number of atoms.

[00:29:20]Is this particle okay or is it the same again?

[00:29:22]That's what I asked for, one mole of C2, one mole of C2.

[00:29:27]So how many months are there going to be? If we have 2 months, Calculate how much K will be 44 grams.

[00:29:33]However, the simple thing to understand is that Don't create any confusion for yourself.

[00:29:38]There is a dozen information, there is a village information, you know that.

[00:29:40]We use it a lot in daily life.

[00:29:42]It's become a family, but the concept is the same.

[00:29:45]The price is only the amount of all the small things.

[00:29:47]We use it to make things bigger, then Let me give you one mole of water, one mole Let's give one mole of C2. Let's give one mole of methane.

[00:29:54]A mole is something to keep in mind.

[00:29:56]Want 6.02 Ray Path Molecule Ions Particles or Asked for a mole in the form of mass What is the mass of water? One mole of 18 is 2.

[00:30:08]How many months were there? 44. Know these things.

[00:30:10]It should be okay, I'll see you again.

[00:30:12]I understand the question and tell you more.

[00:30:14]Things will clear up.

[00:30:16]Look at the writing here, there is another concept inside.

[00:30:19]It will be clear to you, look at these many letters here.

[00:30:22]Off oxygen STP STP means stad Temperature and pressure are required.

[00:30:31]Completely 2.2 grams of propane is fine.

[00:30:35]Now what about 2.2 gum propane?

[00:30:37]If you have him, you must make him completely If so, how much oxygen should there be, but in what?

[00:30:43]Ask in liters now.

[00:30:46]I'm going to tell you another concept.

[00:30:48]Write down the mole equal somewhere along with it.

[00:30:51]One mole equals 22.4dim You can write it as C or as One mole equals To 22.4 Liter liter and DM q are the same.

[00:31:08]Okay, that's all you need to remember.

[00:31:10]Step by step, now we calculate.

[00:31:13]Let's do it, how do we do it?

[00:31:15]To be complete, you have to do the reaction.

[00:31:18]What is the formula of propane?

[00:31:21]Hydrocarbons should be remembered by name.

[00:31:24]Finally, who would be the alkane?

[00:31:26]The formula of propane is C6H Carbon C6H You will remember what to do, who to talk to.

[00:31:33]Will react Will react with oxygen Any carbon present in carbon If you are going to burn coal, what are you ready to burn?

[00:31:39]What is being prepared along with C2?

[00:31:42]Hydrogen present means water is formed.

[00:31:44]It's okay if you write a reaction to what used to happen.

[00:31:47]Where is this note, let it be methane, let it be propane?

[00:31:50]What is a hydrocarbon?

[00:31:52]Compounds containing carbon and It's okay if hydrogen is present, it's different.

[00:31:56]The topic is somewhere in the next lecture.

[00:31:57]Let's cover this in the B reaction balance.

[00:32:01]The chemical equation should be: How much carbon I see three, how much carbon is there here? Let's go.

[00:32:05]Let's complete three carbon C2 hydrogen There are eight hydrogens.

[00:32:11]How much oxygen will be produced from water? Four are produced.

[00:32:14]Okay, four oxygen, four and here.

[00:32:17]How much will seven be here? How much will five be here?

[00:32:20]Must be able to write a balanced chemical equation.

[00:32:23]Another law is the law of conservation.

[00:32:27]The off mass is the same as the reactant mass.

[00:32:30]The product should be a balanced chemical.

[00:32:32]Solve such questions by writing equations.

[00:32:34]It's okay to want to balance this.

[00:32:36]The equation is written, okay, now look here.

[00:32:39]When you burn propane, How much oxygen does propane need for buns?

[00:32:45]Kids, five, what's the next number?

[00:32:48]Representing moles, how many moles are needed?

[00:32:51]Five moles of oxygen means one to me.

[00:32:54]If propane has to be completely shut down Now they need five moles of oxygen Wonder how many liters of oxygen Required, please remember this now if I need to turn off one mole of propane.

[00:33:07]The propane is off. Is there anything in front of it?

[00:33:09]I'll make it a little bit here, if it's a bit.

[00:33:12]There is nothing here, what is one digit, one mole of If propane is to be completely burned, five I know that moles of oxygen are needed.

[00:33:20]Okay, I'll remember that now.

[00:33:22]Represent propane in its mass Should we do it or should we represent it in liters?

[00:33:26]Okay, mass mass 2.2.

[00:33:29]Calculate the molecular mass of propane.

[00:33:31]It is necessary to do this, we calculate it here.

[00:33:33]C3H How many carbon three three points 12 plus How much hydrogen is this? Let's say hydrogen is 12.

[00:33:43]What happened to 36 plus A? What is going to happen to 44?

[00:33:48]Propane molecular mass is 44 one mole Grams One mole is how many grams 44 grams When propane needs to be burned How much oxygen was needed? Five moles of oxygen.

[00:34:00]Oxygen means how much oxygen will you take now?

[00:34:03]We want to calculate the value in liters.

[00:34:05]One mole is how many 22.4 five moles What will be done 22.4 This will be the standard Chemical reaction, children, but now 44 grams Why is it given to you, not to you? How much is it given to you? 2.2 Propane is when you add 44 grams When burning propane, oxygen is needed.

[00:34:25]I wanted to see the price, but what did they say?

[00:34:27]I don't have 44 gum propane available.

[00:34:30]How many grams are available? It is 22.4 again.

[00:34:33]Look, I wrote 22.4 in Grammar.

[00:34:36]Written here is 22.4.

[00:34:42]22 is 4 now 22.4 why do you need the answer If you want it in liters, look here now.

[00:34:48]When I was closing 44 grams of propane I wanted a five-molar option, but I don't have one.

[00:34:53]Now is propane 44 or not 2.2 so I What will you do by calculating the number of moles?

[00:34:57]How to calculate the number of moles Here you can see how much is given for the given mass 2.2 Decided by molecular mass 44 Let's calculate Let's do this. Let's consider minus and here.

[00:35:10]If only they had.

[00:35:13]What is the difference between the plus and minus of the number 1 and the minus of the number 2?

[00:35:19]Come on, zero, now look here, how much is it?

[00:35:24]2.2 means how many z pz.0 How many five per mole given zero f moles?

[00:35:32]If the mole of oxygen is zero, how much is zero?

[00:35:36]You need to understand this to make calculations.

[00:35:39]All that is needed is the rest of the calculations, which are very easy to do.

[00:35:41]I'm a little rough on all of this.

[00:35:43]I do this.

[00:35:46]Look here, let me explain it to you again.

[00:35:51]When I was closing a mole of propane Then I needed f moles of oxygen but How many moles do I have? Now pay attention here.

[00:35:58]How much is five moles of oxygen per mole?

[00:36:00]I have moles given in the question, how many 0.0 Zero F is an option but how much will it cost if F is in one?

[00:36:10]How many fives for amant and what for zero paf?

[00:36:13]You will do cross multiplication.

[00:36:14]If you can do it simply, what will you do with the cross?

[00:36:16]Do multiplication and you will understand.

[00:36:18]If it goes, then cross multiplication fuzz.05 What is coming up 25 25 How many z.25 options It will take a while, but how much is a price option?

[00:36:31]22.4dm Deem C You will get the answer DM Cube What if I want it in liters?

[00:36:37]That means 22.4, how many options are available to you?

[00:36:41]Z.2 F means Fo here but you cross You can do multiplication crosswise.

[00:36:48]Multiply what is coming?

[00:36:51]Sorry.

[00:36:52]This is z2, so what is this going to be? Cross it out.

[00:36:56]Will the multiplication answer be found or Z.25 is mv4, so 22.4 Do that, the answer will be found, come on, I'll write it here.

[00:37:04]There is a little less space, 22 p. deeded by fo.

[00:37:07]Let's do it.

[00:37:10]Five 20 How much is six ek two f 24 5. C Answer It should be 5.6 liters, but there is less space.

[00:37:19]Because even if this happens a little, I will tell you.

[00:37:21]I'm explaining everything once and for all.

[00:37:26]Look here, babies.

[00:37:28]What is this mole? What is this standard chemical reaction?

[00:37:31]What is the formation of oxygen if written C6 HTF?

[00:37:35]How much C2 will be produced? How much water will be produced?

[00:37:38]If so, then four water is the standard chemical.

[00:37:40]The reaction is when 44 grams of propane When there are f moles, f moles are in liters.

[00:37:46]Will drink 22.4 liters The reaction is a standard chemical reaction but Why don't you have 44 hearts and 2.2 hearts?

[00:37:54]You are asked to calculate this value.

[00:37:56]Things you can do with cross multiplication Let's calculate that at 44, this much How much is going to be there when it is 2.2, that is, 244 So how much is one mole of 2.2? How much is 0.05?

[00:38:09]A five mole option is required when moles is one mole was 0.05 How much will the option cost when it is in the money?

[00:38:17]How many times would you have come after answering?

[00:38:19]Calculated 22.4 and 4.

[00:38:23]5. Remember that the answer C was coming.

[00:38:27]The purpose of the question was to show that If the commission asks such questions So first balance the chemical equation It was necessary to write, okay, how is this again?

[00:38:37]If you come across this, please tell me again.

[00:38:39]I have 2.2 hearts, why did I write 2.2?

[00:38:42]How much oxygen is needed when making bread?

[00:38:45]Okay, 2.2 F means how many moles of Z.Zero F?

[00:38:49]It's worth writing your standard reaction.

[00:38:51]So what happens is that one mole of propane is five There was a mole of oxygen, but what is the mole here? Z.05 So after calculating how many moles of oxygen How much oxygen will you need? 2 hours 25 There is 0.25 moles of oxygen required.

[00:39:09]Z.25 What is the mole of oxygen required in liters?

[00:39:13]What is one mole in liters?

[00:39:16]That is, 22.4 liters, then how much is 22.4 liters?

[00:39:21]After litter cross multiplication How many times do you get an answer? 5.6 Try to remember that Types of questions you will get in the exam But be careful what you ask.

[00:39:32]Remember the data.

[00:39:34]Here is another question of the same kind.

[00:39:36]I have taken you to clear the concept.

[00:39:37]Okay, kids, look here, calculate the mass of Carbon dioxide and water form on Complete combustion of 24 grams of methane is See a little e question now written methane First, write a standard chemical reaction.

[00:39:54]The choice to take is said to be with the option.

[00:39:56]What will be the reaction C2 Plus produced?

[00:39:59]Is water H2O? Remember the carbon balance.

[00:40:03]Do it, hydrogen is four here, do it here.

[00:40:06]Two options, two options, what to do here?

[00:40:08]This option will be done with four COs.

[00:40:12]It is necessary to have a balanced chemical equation, otherwise The answer will be wrong. Now see what he said Calculate the mass of CO2. How much carbon dioxide?

[00:40:19]What oxide will be formed and how much water will be produced?

[00:40:21]It will be asked whether complete combustion of 24 g of Methane. Now look at the molecular mass of methane here Can you calculate? Carbon is a plus How many hydrogens are there? Make four. How many hydrogens are there?

[00:40:32]Coming? 16 comes in 16 in a mole now here Look, I wrote down the standard chemical reaction.

[00:40:37]How much is this? How much is 16 options?

[00:40:40]32 32 th do 64 How much CO2 was produced then? How much CO2 was there?

[00:40:48]44 Water is going to be 18 and 36, see this This standard chemical reaction is written as When you burn 16 grams of methane How much oxygen is needed when doing 64 How much carbon dioxide is being produced then?

[00:41:01]44 How much water is being produced? 36 is being produced.

[00:41:04]You may ask, why didn't you give 16 now?

[00:41:07]If methane is 24 in place of 16, then Tell me how much CO2 and how much water.

[00:41:12]It won't matter if it is.

[00:41:14]Simple I know when 16 methane How much CO2 is produced when burning 44 So how many cross multiplications are there when there are 24?

[00:41:24]Can you do it? I'm a little short on space.

[00:41:27]I'll do it and then explain it to you here.

[00:41:29]Look, I have to calculate here when I'm 24.

[00:41:32]Look here how much C2 was there when methane was 16.

[00:41:36]How many crosses are there when 44 is 24?

[00:41:39]Multiply what will come out is 44 points What will happen if 24 is divided by 16? Let's divide by four.

[00:41:45]Can four F 16 four S 24 11 G 66 then how much CO2 will be produced in the same way as CO2.

[00:41:55]In the case of water, children Look here if H2O is forced to 16 methane water How many how many are ready 36 are ready 36 what If you write two moles, look here 16 How many votes are there for 36? If it is 24, then how many?

[00:42:09]Cross multiplication 24 times x again We will do 36 points divided by 24, 16 fours, 16 fours.

[00:42:17]How many 24 fours will make 36?

[00:42:22]54 will be prepared How much water will be prepared 542 How much is going to be prepared 66 This is something like 36 36 How many 24 36 here?

[00:42:34]Ch 16 Ch Ch 24 Ch 4 Ch Okay, 54, remember how much C2 and how much water.

[00:42:41]It will be ready in such a way that you Must be able to write a balanced chemical reaction Look here I balance chemical reaction methane so When C2 44 methane was given, how much did I get at 24?

[00:42:53]How much do you calculate in this way?

[00:42:55]Or if you can do it in another way If you have to do it, remember it like this Give When one mole of methane is burned How much CO2 is produced? One mole of CO2 is produced.

[00:43:07]Now 24 given Now 24 given In mole Can you calculate this or that?

[00:43:12]I can write like this in another concept.

[00:43:14]How much is one mole of methane in mole form?

[00:43:18]Given one mole of CO2 and two moles of water Can I write it in mole form?

[00:43:25]I can, but why didn't you give me a price now, ma'am?

[00:43:28]Given that you can calculate the value, calculate how much.

[00:43:30]Given mass divided by molecular mass How many are there in 16? Calculate with a calculator.

[00:43:40]How much is a deeded bytu worth? It comes to 1.5 bytu.

[00:43:43]So 24 grams is how much is 1.5 moles?

[00:43:47]So one mole is one mole, so 1.5 moles How much is 1.5 moles? 1.5 Why don't you ask me in the answer key?

[00:43:56]Asked in Mass2 One mole is how many 44 moles of C2 So 44 is 1.5, so how many times 44?

[00:44:06]What will you do? 1.5 F will do the same way.

[00:44:09]When one mole of CO2 displaces methane in water How much two moles then if one and a half moles are given now I appreciate your 24 hour conversion.

[00:44:17]How much water will be in one to two?

[00:44:20]So how much is one and a half going to be three, so how much is it here?

[00:44:23]Three moles of water will form one mole of water So how much is 18?

[00:44:28]How many three is coming up? If it is coming up to 54, You could have solved it both ways.

[00:44:33]Question in mole form or gram This should be known from the form of 24 So how many moles are there in 1.5 moles of methane?

[00:44:41]There is one carbon per mole, children.

[00:44:44]How much carbon dioxide is in one and a half moles?

[00:44:45]One and a half moles of dioxide and two moles of water How many molecules are there in one and a half moles of water?

[00:44:49]Molecule Three water molecules mol Conversation Answer Gram asked in mass A mole of a person will do the conversion as asked.

[00:44:57]How many moles of CO2 are there? 44 is one and a half moles.

[00:45:00]Calculate one mole of water.

[00:45:02]How many were 18? How many are 54?

[00:45:04]You can solve it both ways.

[00:45:06]Follow the method that you find most convenient.

[00:45:08]It is important to answer the exam correctly.

[00:45:11]Okay, let's continue.

[00:45:14]Now comes another question I asked a question but the number is off here.

[00:45:20]Along with the concept of mole, you will also learn the Law of Fade.

[00:45:23]You should know what the Law of Fade is now.

[00:45:25]It says when you go from a solution Amount of substance passing current How much is the deposited amount of charge pass?

[00:45:35]How much charge do you get from that solution?

[00:45:37]It depends on whether he passed or not.

[00:45:40]Now remember how much amount is going to be deposited.

[00:45:42]Let it be, how can I pay attention?

[00:45:44]I'm telling you a little bit of a joke.

[00:45:47]Amount of Amount of Substance Deposited Amount of substance deposited directly What is the solution to the proposed charge pass?

[00:46:02]So this is related to Faraday's First Law.

[00:46:06]You will be tested by the commission.

[00:46:07]The question asked was whether the amount Of substance in a solution you It depends on how much charge you pass.

[00:46:14]Now we are talking about current electricity.

[00:46:16]What is meant by I current?

[00:46:18]I will write a comment on the one who had a bottle here.

[00:46:21]Can it be that who means who will be?

[00:46:24]If it is going to be, I can write it like this.

[00:46:26]If so, how much amount will be the minimum deposit?

[00:46:30]Who would depend on current and time?

[00:46:33]Now, for this amount of substance, we Let's take small A to represent this.

[00:46:39]Here is a constant to extract the constant.

[00:46:41]The constant that is being taken is called Electrochemical equivalent m It is directly proportional to z, so now it is here.

[00:46:51]I will write equals by removing the constant, which means hazard.

[00:46:53]There is electro Chemical Equivalent Now, consider Fade's Law I am trying to make you understand.

[00:47:03]Remember what the devil says.

[00:47:06]Amount of funds deposited directly Prop Proportional Charge Pass Charge Why Me IT If you write charge in place, look here for the current.

[00:47:14]You know where to go now.

[00:47:17]To eliminate proportionality, you I use constant, I call it that.

[00:47:21]Remember the electrochemical equation What is this electrochemical equation for?

[00:47:26]Let's remember here that nose means How is electrochemical etching done?

[00:47:31]If you want to solve it, it's simple.

[00:47:33]What is electrochemical equivalence?

[00:47:36]What is the mass now molar mass for the compound If the element is atomic mass divided by Valence Divided by Valence Molar mass divided by valence in f That is, the Faraday constant is electrochemical.

[00:47:55]Value of constant YAZD molar mass Divided by Valence in F is the same as Fade.

[00:48:01]Remember that question.

[00:48:03]It will be necessary to remember this.

[00:48:05]Mass deposited depends on who is current.

[00:48:08]It depends on time and most of all The important thing is going to depend on the valance.

[00:48:12]Let's continue with the question now.

[00:48:14]The question was asked here again, Commission.

[00:48:18]One current of Huppert Pass molten sodium chloride fur Na65 sec If you give the option below, it will tell you.

[00:48:28]This much current and for this many seconds If you pass, how much chlorine and how much Sodium deposits are calculated.

[00:48:36]Now, look here, what kind of current they have.

[00:48:38]How much current is given, how much time is left?

[00:48:42]I have given 965, now look, now we have one.

[00:48:45]What charge was the formula written for?

[00:48:47]How to calculate formula charge?

[00:48:50]How much current is given? Happy hour.

[00:48:54]How many times 965 is multiplied by these two?

[00:48:57]True 96500 What does 9650 charge mean? 9650 charge means If there were children, one fade would be here, one lakh fade.

[00:49:08]I don't remember where the value is.

[00:49:12]One Fade Almost Equal Value One Fade Now That's all you have to give and ask for.

[00:49:17]How many numbers will be deposited now?

[00:49:20]Remember here that in Fared's law, the number of Amount deposited or number of amounts A formula for deposited Remember the Equal to Amount formula To keep c divided by n * a formula What am I saying is n n is the number of moles q.

[00:49:41]So who is going to be the four deeded * f this one Let the formula be the number of moles.

[00:49:46]What did I do in the comparison? Faraday's There is a law and we value it in relation to it.

[00:49:51]Let A is number of moles and C is four You can also write IT in four places.

[00:49:56]And A means Valence, remember that.

[00:49:59]Valence is a city for Valence Fade.

[00:50:03]Now let's look at this question: What is current?

[00:50:06]The same current is passed 96 times.

[00:50:11]How is the value constant remembered here?

[00:50:13]What will be the chances of Valence A plus Sodium?

[00:50:16]Is C A minus A you molten solution?

[00:50:20]If you add them, you get A plus and C minus.

[00:50:23]Now, let's look at these two simple formulas.

[00:50:25]I must have noticed for you.

[00:50:27]Molton in real time for you now Understanding what reactions occur in solutions I say, if you have one, you have two types of one.

[00:50:34]What is going to be the anode and the other the cathode?

[00:50:39]How is a node a node? It is positive now.

[00:50:42]Who would react positively on the node?

[00:50:44]Who will go to cl- cl- What will you do? It will take two months to reach the node.

[00:50:51]Chlorine gas will be deposited into two electrons.

[00:50:53]What happens if the cathode is negative?

[00:50:56]Who will go to the negative terminal?

[00:50:58]Sodium A plus will gain one electron.

[00:51:01]What to do if sodium deposits form?

[00:51:04]Remember positive cathode negative Look here, electron loss occurs.

[00:51:09]Loss is oxidation electron gain.

[00:51:12]Becoming means reduction is a different part Yes, but keep in mind that you What are you doing, same current, same time period?

[00:51:19]If you ask how much deposit you can make, Keep in mind that when both The continuity is the same and what do you calculate?

[00:51:26]Had done 96 foloms It is charged, that is, how much is one charge?

[00:51:32]Now when you charge a penny, If you pass the solution, how much is it?

[00:51:38]If you make a deposit, the amount deposited equals Gram Eq is okay now remember that I said sodium goes to the cathode plus How much sodium is one mole of sodium?

[00:51:51]There is going to be a deposit, now there is a price.

[00:51:53]What is the mass of sodium if one mole is 23?

[00:51:56]So, tell me, what is the atomic mass?

[00:51:58]How much will a mole deposit cost? 23 ready But how much chlorine will be in it?

[00:52:03]Chlorine is being deposited, cl2 chlorine gas If you want chlorine in the given option If asked, you would have written 35.5.

[00:52:12]Look here, if you had asked for chlorine, you would have said chlorine.

[00:52:14]What is the mass of one chlorine atom? 35.5 I asked how much chlorine gas, now chlorine gas So how much is going to be 71 but How many farads do you have? One farad One farad What are you going to do if 35.5 Pa is doing what?

[00:52:31]Chlorine is being deposited, simply remember Let it be, where did it come from, current and time?

[00:52:37]One-time deposit multiplied by one-time deposit How to calculate the amount of substance in grams?

[00:52:47]Jatano molar mass divided by valence now What is the molar mass of sodium?

[00:52:52]What will be the atomic mass and valence of sodium?

[00:52:55]What is one divided by 23?

[00:52:57]Coming means 23 coming here here But why was chlorine gas given as an option?

[00:53:02]What is chlorine gas in CL2?

[00:53:05]How much chlorine will be deposited per farad?

[00:53:08]So it becomes 35.5 or 71, remember?

[00:53:12]How much sodium will be 20 and chlorine 35.5?

[00:53:15]Option number one is a bit complicated.

[00:53:18]It seems like you're wasting time.

[00:53:21]If you don't have it, just remember.

[00:53:23]If asked in the exam, what will you remember?

[00:53:26]If you want to keep this in mind, keep these two or three things in mind.

[00:53:28]Give the amount of money deposited directly.

[00:53:31]You can get a proportional charge pass from him.

[00:53:34]Remember the equation to draw the equation.

[00:53:37]Means electrochemical current in time Moler will calculate the electrochemical equation Mass. Deed Bynes Fade constant remember the symbol here now In this condition, the cathode and anode are molten solutions.

[00:53:53]What was the reaction, simple mind?

[00:53:56]One mole used to pass through one fada.

[00:53:58]How much chlorine sodium will be 23 and How much chlorine will there be? 35.5 Continue Let's do it.

[00:54:06]Look at the very nice illustration of mole fraction Let's continue. What is the mole fraction here?

[00:54:12]Remember it is the number of moles of a particular component to the total number of moles of the Solution is a particular component of a total.

[00:54:23]What to do with the number of moles of solution?

[00:54:26]If the substance in the substance is a Mole fraction mole A B then that Calculate the mole fraction of the given substance.

[00:54:37]Moles of divided by total moles of Solution Simply, whatever you need in the exam Asked for mole fraction, its moles are above You want to write the total moles divided by Remember this for the solution example.

[00:54:51]Things to solve theoretical data problems You will understand better here.

[00:54:56]Mole Fraction of A as Asked Number of Moles of divided by number of moles of Total Solution AB Here two components If you take more than two, you Could have taken two more components.

[00:55:11]Here is a question that you can understand from the beginning.

[00:55:13]Things will go.

[00:55:15]Gum of methane and gum of oxygen are mixed.

[00:55:22]Not Richter and the mole faction two gill moles What's the point of asking to calculate a function?

[00:55:29]If asked for a fraction, then the mole fraction of Asked for methane, now calculate mole fraction.

[00:55:34]To calculate the number of moles How to calculate the mass of methane How many hearts 32 given mass divided by molar mass What is the formula of methane, ch4? 12 ch 16 This is methane, second only to oxygen.

[00:55:50]What is the mass of gunpowder? 192 Oxygen molecular mass How many are there to consider? 32 consider Okay, let's do the calculation here.

[00:56:00]Take the number of moles of methyl so that 32 is how many moles?

[00:56:04]Here are the moles of methane calculated.

[00:56:08]Let's see.

[00:56:09]How do you divide by four?

[00:56:12]Four four squares 16 remaining three 32 How many moles will be 48? Six moles.

[00:56:22]This is the number of moles of oxygen.

[00:56:25]Calculate the number of moles of methane.

[00:56:27]Why not calculate mole fractions?

[00:56:29]It's something to do, but it's important to remember that methane is a byproduct.

[00:56:32]I'll rough it up, but remember that now.

[00:56:35]How many moles of oxygen are there? Moles of 2 are six.

[00:56:38]How many moles of methane are there in moles?

[00:56:41]We are asked to give more mole fractions.

[00:56:44]Why are you asking here, Lil Mi Mole Fraction of Methane whose mole fraction is mole fraction The mole fraction of methane asked for Its number of moles is to be taken above.

[00:56:55]What is the mass of methane to be deeded by total?

[00:56:58]What does moles mean in total moles plus si?

[00:57:02]Plus C, how much will it cost?

[00:57:06]How much will the deeded by Fo yield in mole fraction Z2?

[00:57:09]F So mole fraction of methane is 2.2 f so mole Remember the fraction simple, which Asked for mole fraction, its number is off.

[00:57:18]Moles above divided by total moles of The solution will be remembered, this formula is here Remember what you wrote carefully again.

[00:57:25]Tell me that mole fraction is another concept.

[00:57:28]Remember you need mole fraction A plus B is the sum of the mole fractions of the two One Total Mole Fraction What is the total mole fraction A plus B?

[00:57:42]The forest should come first, methane is 0.25 So how much oxygen should we get? 0.75 Okay, this is a little bit of additional data.

[00:57:51]Remember, look again, this is another one.

[00:57:54]He asked the question again on the platform.

[00:57:56]The question is, what do you need here for fruit?

[00:57:59]Read the given question and show once one amp.

[00:58:01]An electric current passes through one mole of one mole Kc One molar rubbed chloride solution for one Second the correct relationship for the number of Moles of Metals Deposited Now You I was going to explain the formula and say that the number is off.

[00:58:19]Moles and the Fatigue Loss Equation are here to remember.

[00:58:22]Number of moles Equal to k divided by valance In Fade's Const This formula is based on the number of moles and the number of How many number of moles is the Law's relation What is deposited? Depends on whether it is I or Ya.

[00:58:41]What can you write in place of I?

[00:58:44]You can write "Ati" instead of "Divided by Valence".

[00:58:48]In Faraday constant is constant change.

[00:58:50]Is it going to happen or not? Okay, so what now?

[00:58:52]What is the current of one ampere in cm?

[00:58:55]How much is the current time in one second?

[00:58:57]And it is the same, now it is also consistent.

[00:59:00]Ural who is Valence, look at the AC The valence of sodium is one and the valence of potassium is one.

[00:59:06]One rubidium has a valence of one, all three of them.

[00:59:09]Which group are the elements in?

[00:59:10]There are elements of the first group, so now come Complete Formula Number of Moles Equal Atty Died By Valance F Constant Current Sem The time is the same, the valence is the same, but if How many number of moles will be deposited equal to If moles are deposited, then option number Which one is going to be option number three?

[00:59:30]This formula should be noted down somewhere.

[00:59:32]Give the number of moles deposited.

[00:59:35]Equal to Divided by Valance in Fade What can you write in place of the consonant C?

[00:59:42]Given current is same, time is same, Fadi The constant is already the same, but the valance How is everyone doing? If yes, how much?

[00:59:50]If there will be deposits, then there will be equal deposits, okay?

[00:59:54]This is a simple relationship. I told you before.

[00:59:56]I will explain this relationship in a moment.

[00:59:58]And this is Faraday's law, but this law is a little bit Remember, it will be asked in the exam.

[01:00:04]Look further, there are two more concepts, one Molarity and one molarity are very different.

[01:00:08]Important concepts were again introduced by the Commission.

[01:00:09]Asked about this again What is the most important thing to remember?

[01:00:13]Write down these formulas and see what the values ​​are.

[01:00:16]What is molality? Moles of solute divided By Volume of Solution in Liters Moles of Sol Deceded by Kilogram of Solve Two Mah The most important symbol is molarity capital.

[01:00:27]M molality small here unit moles per liter The mole per kilogram formula is important.

[01:00:34]Remember the formula, we will move on.

[01:00:36]Let's continue, the most important thing is to see more.

[01:00:39]Normality will be asked in the exam.

[01:00:42]Above all, normality is the most important thing.

[01:00:45]gram equivalent of solute divided by Volume of solution in liters is the largest It is important how to calculate gram eq Will do mass of substance in village divaded Given the formula for equivalent mass mole We were doing mass dead by molar mass here.

[01:01:02]What is the mass of substance divided by grams?

[01:01:05]Excellent weight is the most important thing here.

[01:01:08]Remember the normality and molarity relationship.

[01:01:11]Let normality equal molarity.

[01:01:15]A question came up about a formula called factor.

[01:01:18]Asked about normality and molarity relationship Molarity n factor is the most important Normality Gram of Solt Divided by Calculate Volume of Solution in Liter Grams Kel jatano mass of sub divided by ix How to calculate the weight of an object given mass?

[01:01:38]Things that are done by factor are fine.

[01:01:41]I will explain to you first.

[01:01:42]Let's look at the formulas for normality and Molarity relationship Molarity n factor is n What is replaceable H for factor cid?

[01:01:52]What is replaceable minus for bases?

[01:01:55]Irons here again formula normality Molarity Basicity Acid for base for which one?

[01:02:02]Formula Normality Molarity Acidity or Remember the simple formula below.

[01:02:08]Reproducible mass for SID Reproducible base Eincer for Sid for Base Normality Eql Molarity in n factor a factor Now you So if there is no sirsid and base, then the rest Valances used in places Okay, remember the formulas.

[01:02:27]Wanted children, now again how is the Eclent mass Calculate Gram Eq Calculate Jat Caste Gram Mass of Substance Divided By Ict How to calculate molar mass divided by factor?

[01:02:43]And the atomic mass for the element is divided by Valence is the most important formula.

[01:02:48]I'm telling you numerically.

[01:02:50]Things will be understood now, I asked a question here.

[01:02:52]What would be normality?

[01:02:57]Solution Prepared by Ling Pho. Gum off in f Liter of solution is the most important Normality means you have a formula.

[01:03:06]We must remember the formula of normality, Gram.

[01:03:10]of solute divided by volume of solution liters First of all, it should be here, give me a liter.

[01:03:16]What is the milliliter in milliliters?

[01:03:19]How much will it cost in liters?

[01:03:22]It is a liter because how could it be one liter?

[01:03:26]How many thousand milliliters are there in 0.5 liters?

[01:03:30]It's coming, okay, just remember that.

[01:03:32]This conversion is 0.5 liters, the first clear What happened to the second normality? Moles of Solut Gram Inc Will do mass off Molar mass will calculate x and x By factor, now let's look at this question H24 What is the Sid Kaas will remove Iq mas eklant mas Equal Molar Mass4 How to calculate molar mass?

[01:04:03]How much is the dividend by factor H2 A4?

[01:04:08]Two hydrogens can be produced in a reusable way Look, there are two, so how many bytes are divided?

[01:04:13]Will come Ik mas 4 Na ha jale Ik mas We must draw you out, Gram Eclectic Gram.

[01:04:21]Equivalent Mass Gram Eq Mass Cs How much will be calculated for a given mass?

[01:04:26]Is 4.9 Divided by X How many times can you divide 49 by how many?

[01:04:34]The wind is coming to this village this month.

[01:04:39]Let's derive the formula for normality.

[01:04:41]What was the village?

[01:04:45]Zav deeded by volume of solution in liter z What is coming and how many answers are there for Dead by Daylight?

[01:04:53]Will come 2 I will remember you again.

[01:04:58]I understand the question and I'm asking you.

[01:05:00]The formula for normality is normality for you.

[01:05:03]Everyone should know about moles.

[01:05:04]Solute in liter divided by sorry gram eq of Solt Dead by V of Solution in Liter First time converting to milliliters What will you convert to liters?

[01:05:14]The second equinox will be remembered most.

[01:05:17]How to calculate molar mass?

[01:05:20]Divided by a factor of SID What is the N factor of sulfuric acid?

[01:05:24]How much sulfuric acid would have a molar mass of 98?

[01:05:27]All I need is a month, don't you?

[01:05:32]How do you calculate it?

[01:05:35]Mass Deed By Sorry Given Mass Deed By This month's sex How much is the answer to Z2?

[01:05:45]It's coming, just remember.

[01:05:47]The problem is, why did I take it a little too fast?

[01:05:49]The answer I wrote is the solution for you.

[01:05:51]How much is coming? Zero.2 would have been normal.

[01:05:54]Here is the PDF for you.

[01:05:56]If you want PDF, go to Gyandeep Academy.

[01:05:58]Download the app and you will get a PDF.

[01:06:00]These notes will be found in the section Welcome, so let's talk a little bit quickly.

[01:06:05]I understand this question for you.

[01:06:07]I wanted to say this because the commission asked for it.

[01:06:09]The question is, I read the question for the first time.

[01:06:11]I tell you, we will continue, children.

[01:06:14]How is one normal H2 A4 solution prepared From 10 dm cube of 1.5 f molar H2so4 Solution They told you that Dad is a 1.5 What is the molarity of a 24 molar solution?

[01:06:33]You need to convert one normal H2O4.

[01:06:35]In the solution, how do you do it?

[01:06:38]If you can, remember here now that you are one I had seen the formula, normality.

[01:06:45]Equal to n factor into What did you see, molarity?

[01:06:54]So now here we have the molarity.

[01:06:56]If you want the answer for normality What will be the factor for Sid?

[01:07:02]Given molarity, how much is 1. Convert f?

[01:07:06]The normal solution is coming, it will come first.

[01:07:09]I know the formula to do the conversion.

[01:07:11]Was the normality factor molarity a factor How many for how many all three normal Will you remember the solution first? I will rough it.

[01:07:23]Takes We have three normal solutions.

[01:07:26]Normal Now, what kind of data do you have?

[01:07:31]How much is the personal one and how much is the normal v1 one?

[01:07:36]They will have a volume of 10dm.

[01:07:39]Now we ask you, is there such a solution?

[01:07:41]What is the normality of the solution to be made?

[01:07:43]If you want n1, how much n2 will you take?

[01:07:46]Calculate v2 inside it, it says How can you change this?

[01:07:52]To remember, look at the equation.

[01:07:54]The dilution equation is called dilution What is the equation, then simply C1?

[01:08:01]I write these things down a little bit.

[01:08:03]I am writing here for you the dilution.

[01:08:05]Equation A1 C1 E2c2 This is called the dilution equation.

[01:08:13]We say that the dilution equation is A1 A What's going to happen, please remember this. Sorry1 Should be v1 c1 = v2 c2 sorry volume Initial volume initial c1 ie Concentration is the final volume c2 That is, the final concentration is called the dilution.

[01:08:32]We call this dilution equation the equation We change as needed. What do we need now?

[01:08:37]I want normal, I want to remember here.

[01:08:39]Equation and E A2 We changed that dilution equation.

[01:08:48]Why can you do it for normal?

[01:08:51]Why is that?

[01:08:53]But you could write the dilution equation Now just how much is the value?

[01:08:58]How much is A2? How much is it? He already gave it.

[01:09:01]I want one normal, how much volume is required?

[01:09:03]Let's consider you X.

[01:09:06]Multiplication here and division there, three points.

[01:09:08]30 Dead By Daylight is coming, is it coming?

[01:09:10]What is X Chalue X coming up?

[01:09:13]How many will come 30 but now only remember 20 finals Yes, but how much volume do you already have?

[01:09:19]Present is bye bye, not bye.

[01:09:23]Ding Gum Off Nahi Thi See Here By Dingtdim It's B2 in the final, kids, but we're already ready.

[01:09:32]How much is 10 days worth of income?

[01:09:35]How much volume do you want to make? 30 Then the three normal solution conversion What is going to happen in the One Normal Solution?

[01:09:42]How much extra will I get in the middle? If it is 20 DM, I will do it again, I will give you two or three.

[01:09:47]Things are written in this formula, but look here.

[01:09:50]Remember me, normalcy and abundance.

[01:09:52]Relation A factor for sulfuric acid How much is the factor, we are normal?

[01:09:58]The solution is three and this formula is two.

[01:10:03]Or you can remember this as dilution.

[01:10:05]Equation Initial Volume Sew Initial Concentration Equal final volume C2 you are dilution Equations can be written in different ways.

[01:10:18]Dilution Equation Can you write it like this, sir?

[01:10:24]You can write equal M2 normally.

[01:10:28]If you ask me, what did you do?

[01:10:30]And Ill A2 Keep this in mind for molarity.

[01:10:35]If you ask a question, come and see.

[01:10:38]For normality There are simple questions, just a little while reading.

[01:10:43]Carefully remember all these things Try to remember that it's okay.

[01:10:50]I took this question a little too fast.

[01:10:52]Normality but the same explanation You will only meet in notes.

[01:10:56]This little slide is important when reciting.

[01:10:58]Key Eclent Mass Gram Eclect The words They may seem a little similar when reading.

[01:11:03]To remember things a little more carefully Try, the most important thing is where else?

[01:11:07]So the normality molarity relationship and this Two basic formulas are the formula number of You can write IT in place of moles C.

[01:11:16]I is the current temperature divided by How is everyone's balance? Same answer.

[01:11:21]You understand what I said, but this How to remember mole fractions properly And this is Fade's law, Fade's law equation, we Why is it made this way?

[01:11:32]35 if chlorine as chlorine gas deposit If you had asked, you would have come to a different conclusion because We have only one value for C2, which will be 71.

[01:11:41]Fadech 96.

[01:11:43]So option number one is going to be okay.

[01:11:46]And after such questions Solve this question by arranging it properly.

[01:11:50]I want to do it well for you.

[01:11:51]Although the concept is explained clearly If you have any problems, Be sure to tell me in the comments section.

[01:11:57]I'm telling you again that the video Whether the series is beneficial or not If you want another topic or subtopic You are always welcome.

[01:12:05]Can you recommend that sir come to this topic?

[01:12:07]Watch the full series on Sub Topic.

[01:12:10]The purpose is to make you feel important.

[01:12:11]Important concepts Or I will ask the commission questions along with the subtopic.

[01:12:16]Shows what kind of questions they ask.

[01:12:17]You definitely got what you asked for.

[01:12:19]We hope it will be useful. Let's wait.

[01:12:22]Okay, if you like the video, be sure to like it.
