Chemistry is the study of matter and the changes it can undergo. In this first unit of class 11 chemistry, we learn the significance of scientific notation, rules to calculate significant figures, the laws governing the combination of different atoms, mole concept, stoichiometry that involves the study of amount of substances that are involved in reactions, and modes of expressing the concentration of the solution.

What links gas volume to the number of molecules inside it? This video provides the molecular explanation behind Gay-Lussac’s Law through Avogadro’s insight. We explore how equal volumes can hold equal numbers of molecules — regardless of their size or complexity — making gas reactions easier to understand at the molecular level.
