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.
