Answer to my own question using the googles:
Density of Moist Air - an Air Vapor MixtureThe amount of water vapor in air influence density. ... When vapor content increases in moist air the amount of Oxygen and Nitrogen are decreased per unit volume and the density of the mix decreases since the mass is decreasing. dry air is more dense that humid air!
