Vapour density = (density of gas)/density of hydrogen gas

=> Vapour density = (M/Vm)/(2/Vm), here M is molar mass of gas in g, 2 is molar mass of H2 gas and Vm volumes of gases

So, Vapour density = molar mass of gas/2

Vapour density is a unitless quantity


For example :

Vapour density of CO2 is (12+32)/2 





VAPOUR DENSITY ❤️❤️


The ratio of the density of a gas or vapour to that of hydrogen at the

same temperature and pressure.

V.D.=( mass of x molecules of gas / mass of x molecules of hydrogen).
