At 300 mm Hg, a gas has a volume of 380 L. What is its volume at standard pressure?

Explanation:

Given

Initial Pressure = 300 mmHg

Initial Volume = 380 L

Required

Volume of the gas at standard pressure

This can be solved using Boyle's law;

Which states that

Where

Substitute the above values in the Boyle's law equation

 becomes

Divide both sided by 760

Hence, the volume of the gas as standard pressure is 150 mmHg
