Theory

Number Name Description
1. Difference between Atoms and Molecules & Mole concept introduction You can understand the difference between atom and molecule and mole concept by this theory.
2. Mole Concept This theory will help you understand the concept of mole.
3. Calculating number of moles from mass and volume Calculating number of moles of the given substances by different modes has been given in this theory.
4. Calculation of mass from mole and volume Calculating the mass of the given substance from mole and volume is explained in this theory.
5. Calculation of mass from Avogadro's number Calculating the mass of the given substance from Avogadro's number is given in this theory.
6. Avogadro Hypothesis and its applications This theory explains Avogadro's hypothesis and its applications.
7. Calculation based on molar volume How to calculate molar volume is explained in this theory.
8. Calculation of Molecular Mass This theory shows how to calculate gram molecular mass.
9. Calculation based on number of atoms This theory shows how to calculate the number of atoms present in a substance.
10. Calculation based on number of molecules This theory shows how to calculate the number of molecules present in a substance.
11. Percent Composition The percentage composition is just as important to know as the number of entities present in a substance. In this theory, let's take a look at percent composition.
12. Calculation based on percent composition The mass of each element present in 100 g of a compound is represented by its percentage composition. In this exercise, we will practise calculating the percent composition of a chemical compound.
13. Relation between vapour density and relative molecular mass In this theory, the relationship between vapour density and relative molecular mass is explained.
14. Mind map The subtopic of atoms and molecules is illustrated by a mindmap.
