The density of dry air at 20 degrees celsius is 1.20 g/l. what is the mass of air, in kilograms, of a room that measures 24.0m by 15.0 m by 4.0 m?

Explanation:

Density of air = 1.20 g/L =

Size of room is 24.0m by 15.0 m by 4.0 m

Volume of room = 24 x 15 x 4 = 1440 m³

We know the equation

            Mass = Volume x Density

            Mass = 1440 x 1.2

            Mass = 1728 kg  

Mass of air in a room that measures 24.0 m by 15.0 m by 4.0 m is 1728 kg.
