Question

Calculate the density of oxygen, O2 , under each of the following conditions:

Answer 1

The density of oxygen, O2 , under each of the following conditions:

STP 1.00 atm and 20.0°C is 1.78 g/L.

What is the density of a substance?

Density is the ratio of mass and volume of a substance.

The density of oxygen under the given conditions is calculated as follows:

STP = standard temperature and pressure.

standard pressure = 1 atm pressure

standard temperature = 25°C

Volume of 1 mole of a gas at STP = 22.4 L/mol

Thus, 1 mole of O2 occupies the volume , V = 22.4 L/mol

Volume of oxygen at 20°C is calculated using:

V₁/T₁ = V₂/T₂

V₂ = V₁T₂/T₁

V₂ = 22.4 * 20/25

V₂ = 17.92

Hence;

density = 32 g/17.92

Density = 1.78 g/L

In conclusion, density is ratio of mass and volume.
