Class 11 Chemistry – Some basic concepts of chemistry
Chemistry deals with the composition, structure and properties of matter. These aspects can be best described and understood in terms of basic constituents of matter: atoms and molecules. Due to this chemistry is called science of atoms and molecules. But can we study something in science if we can’t measure it? So how we measure atoms and molecules in a sample? Is it even possible? We’ll answer all these questions in this chapter. We’ll learn
1. What are atomic and molecular masses?
2. Mole and its application.
3. What is molar mass?
4. Mass percentage and empirical formula.
5. Balancing chemical equations.
6. What is stoichiometry?
7. What are leftover reactants after a reaction?
8. Limiting and excess reagents.
9. What is concentration?
10. Molarity, Molality, Mole fraction and other concentration terms.
