Question

(I) What is the approximate mass of air in a living room 5.6× 3.6× 2.4m?

Short answer

The mass of the air is 62.4 Kg.

Step-by-step solution

Understanding the expression of mass of the air

The mass of the air can be evaluated with the multiplication of the volume of the living room and the density of the air. The unit of mass can be expressed in kilograms and grams.

Identification of the given data

The given data can be listed below as,

• From the table 10-1, the density of the air is, ρ = 1.29kg/m³.

• The dimensions of the living room is, V = 5.6× 3.6× 2.4m.

Determination of the approximate mass of the air

The mass of the air can be expressed as,

m = ρV

Substitute the values in the above equation.

m= 1.29kg/m³×5.6× 3.6× 2.4m

=62.4Kg

Thus, the mass of the air is 62.4 kg.
