Answer:

1.3g/L is the density of the air

Explanation:

The room is full of air, the space that the air occupy is:

500 cm x 400 cm x 250 cm = 5.00x10⁷ cm³

The density of a substance is defined as the ratio between the mass of the substance and the space that occupy. We can express the density of air in g/L:

<em>Grams air:</em>

65 kg  * (1000g / 1kg) = 65000g

<em>Liters:</em>

5.00x10⁷ cm³ * (1L / 1000cm³) = 50000L

<em>Density:</em>

65000g / 50000L =

<h3>1.3g/L is the density of the air </h3>
