∙ 13y agoNo. Humid air is lighter than dry air. Although liquid water is much heavier than air, when it evaporates it becomes lighter than air. This is because any substance in gas form contains exactly the same number of particles in the same volume. That means that the weight of a gas is determined by the weight of the individual molecules in the gas.
Pure oxygen (two atoms of oxygen) has a relative weight of about 32 whereas pure nitrogen (two atoms of nitrogen) has a relative weight of 28. Pure carbon dioxide 12 +2x16 is 44, much heavier than either. The average relative weight of air being mostly nitrogen (78%) and oxygen (21%) is about 29. Compare that to the relative weight of pure water vapor--18.
When water vapor is mixed in with dry air, the relatively lighter water molecules displace some of the heaver nitrogen, oxygen, and carbon dioxide molecules making the humid air lighter. And the more humid the air is the more lightweight molecules in the mix and the lighter it is.

∙ 10y agoIt is because moist air contains water vapour which is much lighter
