Lecture 10: Combustion analysis | Determine empirical formula | Chemistry Class 11
In this video, you will watch, how to do a combustion analysis and how much carbon dioxide and water are produced. From this data, you can find out the percentage composition of carbon and hydrogen as well as oxygen. On the basis of this, you can find out the empirical formula of any compound you have burnt in the combustion chamber.
Lecture 11: Molecular formula | How to determine Molecular formula | Class 11
This video shows molecular formula descriptions and the difference between molecular and empirical formulas. The molecular formula is that formula which shows the number of atoms of elements in a compound. This formula is very specific for all the compounds in chemistry so it is of worth importance. This video is specially designed for the FSc students for class 11. This lecture also includes examples of the book for convenience.
Lecture 12: Mole | Concept of mole (Chemistry) | Mole-related confusions solved | Class 11
This is a fantastic video describing how the concept of mole in Chemistry works, and what are atoms, ions, molecules and formula units. What are molar mass, ionic mass, atomic mass or formula unit mass? What is the relationship between mole and Avogadro’s number? and many more.
Lecture 13: How many molecules are in ice | Calculate atoms molecules ions bonds in water |Class 11
This video shows how to calculate the number of atoms, molecules, ions and number of covalent bonds in water molecules. This is a calculation or numerical problem where you can find out how many molecules are in the water present in the glass or ice. This is a very simple calculation if you have a little concept then you can find out anything or can solve any problem of chemistry. these calculations are based on a conceptual base not just writing. These calculations are specially designed for the FSC students in class 11 Chemistry.
Lecture 14: Molar Volume | Define Molar Volume | One mole of any ideal gas has the same volume | Class 11
This video shows how molar volume is defined and why different masses of different gases have the same volume occupied. Molar volume is the volume occupied by 1 mole of any ideal gas.
Lecture 15: Stoichiometry | Mole-Mass, Mass-Mole, Mass-Mass Relationships with Numerical | Class 11
This video shows stoichiometry which is a quantitative relationship between reactants and products. This video also shows how stoichiometry is very important especially when we use very costly reactants to make a usable product or a required product.
Lecture 16: Limiting reactant | Points to Determine Limiting Reactant | Class 11
This video shows what is the limiting reactant how to determine it with the use of some important points and how to calculate with the help of a suitable example. limiting reactant is a reactant which consumes earlier and controls the amount of product during a chemical reaction. It can be found with a balanced chemical equation.
Lecture 17: Yield | Actual Yield | Theoretical yield | percentage yield | Efficiency of worker |Class 11
This video reveals very important points connected with yield in chemistry so it tells about what is the yield and its types such as percentage yield, theoretical yield, actual yield and many more. In this video, you can also find out how a worker works efficiently. If you are interested to calculate how percentage yield is determined then this video is for you.
Lecture 18: Class 11 Example 12 Chapter 1| Mg metal reacts with HCl to give hydrogen gas. What is the minimum volume?
Class 11 Chapter 1 Example 12.
Mg metal reacts with HCl to give hydrogen gas. What is the minimum volume of HCl solution (27% by weight) required to produce 12.1g of H2? The density of HCl solution is 1.14 g/cm3.
It is a very important example with a tricky statement, but in this video, you will learn how to solve a such numerical problem.
Lecture 19: A well-known ideal gas is enclosed in a container having a volume of 500cm3 at STP | Class 11
Class 11 example 10 Chapter 1
A well-known ideal gas is enclosed in a container having a volume of 500cm3 at STP. Its mass comes out to be 0.72g. What is the molar volume of the gas?

Really a good work …
Very helpful 👍
Sr need excercise solution for both part
1st year and second year
InshaAllah, I’ve a plan to do massive things for my students. Just keep in touch
Thank you sr
Sir thank you so much
