An apartment has the dimensions 20 m by 10 m by 7 m. The temperature is 25°C, and the relative humidity is 56 percent. What is the total mass (in kg) of water vapor in the air in the apartment?

Answer 1

The total mass of water vapor in the air in the apartment can be calculated using the following equation:

Mass (kg) = Volume (m3) x Density (kg/m3)

Density of water vapor at 25°C and 56% relative humidity is 0.0075 kg/m3.

Therefore, the total mass of water vapor in the air in the apartment is:

Mass (kg) = 20 m x 10 m x 7 m x 0.0075 kg/m3 = 0.105 kg
