Answer:

The mass of air in the room is 91.68 kg.

Explanation:

In order to find the mass of air in the room, given that the volume of the air is 76.4 m³ and its density is 1.2 kg/m³, we can use the following formula:

[tex]\boxed{\mathrm {Mass = Density \times Volume}}[/tex]

Substituting the given values into the equation, we get:

[tex]\mathrm{Mass = 1.2 \: kg/m^3 \times 76.4 \: m^3}[/tex]

        [tex]= \bf 91.68 \: \mathrm{\bf kg}[/tex]

We have that this is an exercise on the density of liquids and gases.

We have that your data is:

  • Volume (v) = 76.4 m³
  • Density (d) = 1.2 kg/m³.
  • Mass (m) = ?

To calculate the mass. We multiply the density by the volume. Therefore, we apply the following formula:

m = d·v

We substitute our data in the formula and solve

m = (1.2 kg/m³)·(76.4 m³)

m = 91.7 kg

Therefore, the mass of air in the room is 91.7 kg.
