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:
Grams air:
65 kg * (1000g / 1kg) = 65000g
Liters:
5.00x10⁷ cm³ * (1L / 1000cm³) = 50000L
Density:
65000g / 50000L =
1.3g/L is the density of the air
