Question

Discuss at least three applications of Avogadro’s law.

Answer 1

1. Determination of atomicity: The atomicity of a gas can be determined by comparing the volumes of gases involved in a reaction.
2. Determination of molecular formula: The molecular formula of a gaseous compound can be determined from the volumes of its constituent gases.
3. Determination of molecular mass: The molecular mass of a gas can be determined by comparing its vapour density with that of hydrogen.
4. Calculation of volume of gases: It helps in calculating the volume occupied by a given number of molecules or a given mass of a gas at a particular temperature and pressure.
