Question 5 5 pts the density of The molecular weight of water in comparison to that of oxygen and nitrogen moist air versus that of completely dry air. O lowers raises

lowers

Explanation:

Moist air have lesser density than the dry air, since,

water has an atomic mass of 18

and diatomic molecule of oxygen, the atomic mass = 32,

and diatomic molecule of nitrogen, the atomic mass = 28.

There fore, considering at constant temperature, the more water vapor that displaces the other gases, the less dense the air will be.

Hence,

The correct option is ' lowers '.
