Best answer

Cl2 has a molecular mass of 71 g. And molecular mass of Air is 29 g .
Relative density of chlorine =( Mass of chlorine/ Volume of chlorine) / (Mass of air/ Volume of air )
Volume of any gas at STP = 22.4 l
Relative density of chlorine = (71 / 22.4 ) / (29/22.4)
Relative density of chlorine = 2.44
