What is the mass of air in a room with dimensions of 6.3×3.8×2.8 m, if, under these conditions, the air density is 1.29 kg / m3?

These tasks: the dimensions of the room in question are 6.3 x 3.8 x 2.8 m.

Reference values: according to the condition ρ (air density in the room) = 1.29 kg / m3.

The mass of air in the room under these conditions is determined by the formula: m = ρ * V.

Let’s perform the calculation: m = 1.29 * 6.3 * 3.8 * 2.8 ≈ 86.47 kg.

Answer: In the room under consideration, the air mass is 86.47 kg.
