To answer the question, pure ammonia has a density of ~0.7-0.9 g/L, depending on temperature. The density of air is ~1.2 g/L, again depending on temperature and pressure. So, yes, ammonia gas is lighter than air in terms of density. 3 people found this useful.
1 Density of ammonia vapor is .5970 pounds per cubic feet compared to air at atmospheric pressure and @ 32Â° F.  Volume: One (1) pound of ammonia vapor occupies a volume of 22.78 cubic feet at 32Â° F and atmospheric pressure. One (1) pound of ammonia vapor occupies a volume of 22.5 cubic feet and yields 45 cubic feet of dissociated gas at a ratio of 25% nitrogen and 75% hydrogen @ 70Â° F and atmospheric pressure.
