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)`. |
