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.
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.
