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.
0.9% argon. 0.1% other gases (like carbon dioxide) Air is well mixed, so we do not usually talk about oxygen being lighter or heavier than air. Helium, on the other hand, is much lighter than air (nitrogen and oxygen), so that is why a helium-filled balloon goes up. At higher altitudes, the air is thinner (less atoms in the same volume), but the relative amounts of nitrogen and oxygen are the same.
