A sample of oxygen gas at a pressure of 1.14 atm and a temperature of 21.5 degrees Celsius, occupies a volume of 815 ml. If the gas is compressed at constant temperature until it's pressure is 1.62 atm, the volume of the gas will be what?

The volume of the gas will be 573.52 mL.

Explanation:

Boyle's law states that the pressure of a fixed amount of gas at a constant temperature is inversely proportional to the volume of the gas.

The equation for Boyle's law is:

P₁V₁ = P₂V₂

We want to know V₂, that is, the volume of the container after the compression. We rearrange the equation and calculate:

V₂ = P₁V₁ : P₂

V₂ = 1.14 atm * 815 mL : 1.62 atm = 573.52 mL
