The vapour density of a gas is 11.2 . calculate the volume by 11.2g of gas at NTP.

Expert Answer:

vapour density of a gas= mass of a substance at STP/mass of a hydrogen at STP 
11.2= 1 gm molecule of a substance/2g 

11.2*2=1 gm molecule of a substance 
22.4g=1 gm molecule of a substance 

22.4g occupies Lt. at STP 
therefore 11.2g occupies Lt.*11.2g/22.4g=11.2Lt.
