Question

The density of air is 1.3k-3 find the mass of air in a room measuring 8mx5mx4m

Answer 1

The Volume of the room is given as V=L×B×H=5×3×4=60m3.

We know, Mass = Density×Volume.

Given that the density =1.3kg/m3.

So, Mass of the air =1.3×60Kg.

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