4. A volume of 20 cubic meters of air has 500 gram of water in it. Calculate the absolute humidity.

25 grams/m3

Explanation:

Absolute humidity (AH):

Absolute humidity (AH) is the mass of water vapour in a unit volume of air. It is a measure of the actual water vapour content of the air.

The formula to measure the absolute humidity is,

AH=

To solve the question, we have

volume = V = 20 cubic meters of air

mass = m= 500 gram

absolute humidity =AH= ?

Solution:

AH=

AH = 500 / 20

=  25 grams/m3
