Answer:

Mass of air is 594.66 kg

Explanation:

We have,

The density of air is [tex]1.29\ kg/m^3[/tex]

Dimension of the room is 4.50 m x 7.88 m x 13.0 m

Volume of the room is [tex]4.50\times 7.88\times 13.0 =460.98\ m^3[/tex]

The density of an object is given by mass per unit its volume. Its mathematical form is given by :

[tex]d=\dfrac{m}{V}[/tex]

m is mass of air in a room

[tex]m=d\times V\\\\m=1.29\times 460.98\\\\m=594.66\ kg[/tex]

So, the mass of the air in a room is 594.66 kg.
