Question

what would be the absolute humidity of air if 1 cu. m. air contains 4.08 gms of vapour at 0 degree C temperature?

Answer 1

Absolute humidity is the amount of water vapour i.e moisture content in the atmosphere, irrespective of the temperature.

Given that water vapour is 4.08 grams and volume of air is 1 cubic meter.

Absolute humidity = mass of water vapour / unit volume of air

= 4.08/1 = 4.08

Absolute humidity is 4.08 gm/m^3

Answer 2

Absolute humidity is the ratio of mass of water vapor to the mass of air in a given volume at a given temperature.

The question can be represented as below

Given in the question,

Mass of air = 4.08 g

Volume of air = 1 cu. m

Temperature = 0 C

Absolute Humidity = 4.08/1 = 4.08 g/cu. m
