Expert Answer:

Vapour density is the density of a vapour in relation to that of hydrogen.May be defined as mass of a certain volume of a substance divided by mass of same volume of hydrogen.

vapour density= mass of n molecules of gas/ mass of n molecules of hydrogen

                       or

vapour density = 1/2 molar mass
