Question

Calculate the mass of air in a room 5 m by 4 m by 3 m. The density of air is 1.3 kg/m3.

Answer 1

Answer:

78 kg

Explanation:

The Volume of the room is given as V=L×B×H=5×3×4=60m  

We know, Mass = Density×Volume.

Given that the density =1.3kg/m^3

So, Mass of the air =1.3×60Kg.

Hence, mass of the air enclosed in the room is 78 kg.
