Why dry air is heavier than moist air?

Answer» Average molar weight of dry air is
`=(% of N_(2)xx28+% of O_(2)xx32)/(100)`
Average molar weight of moist air is
`= (% of N_(2)xx28+% of O_(2)xx32+% of H_(2)Oxx18)/(100)`
Evidently average molar weight of dry air is more and so is its density `(d=M//V)`.
