Calculate the mass of the air contained in a room that measures 2.50 m × 5.50 m × 3.00 m (density of air = 1.29 g/dm3 at 25°C).

Respuesta :

Answer:

Explanation:

Volume of air = 2.5 x 5.5 x 3.00

= 41.25 m³.

Density of air = 1.29 g / dm³

a dm³ = ( 0.1 )³m³

= .001 m³

density in m³ = 1.29 / .001 gm⁻³

= 1290 g / m³

mass of air in the room

= 41.25 x 1290 g

= 53212.5 g

= 53.2125 kg .
