Solution
The correct option is C100g/m3 Absolute humidity is the actual amount of the water vapour in grams present in one cubic meter volume of air. It is expressed in in unit grams per meter cube (g/m3).
So if the volume of air is 5m3 and the amount of water vapour is 500g, the absolute humidity will be (500g)/(5m3)=100g/m3
