What is Vapour density?

Vapour density is the weight of a volume of pure vapor or gas compared to an equal volume of dry air at the same temperature and pressure. It is obtained by dividing the molecular weight of the vapor by the average molecular weight of air thus, it is unitless. It is also defined as the fraction of moles dissociated out of 1 mole.
