What are the main applications of Avogadro's law?
उत्तर
The main applications of Avogadro's law are :
- Explanation of Gay -Lussac's Law
- Determination of atomicity of gases
- Determination of the molecular formula of a gaseous compound.
- Establishes relationship between the relative vapour density of a gas and its relative molecular mass.
- Establishes the relationship between gram molecular weight and volume of a gas at STP.
