The volume of 400cm3 of chlorine gas at 400 mm of Hg is decreased to 200 cm3 at constant temperature. What is new pressure of the gas?

800 mm of Hg
1600 mm of Hg
200 mm of Hg
600 mm of Hg

Solution: 800 mm of Hg

This is an example of Boyle’s law, which states that the volume of a gas is inversely proportional to the pressure at constant mass and temperature.

The equation for Boyle’s law is P₁V₁=P₂V₂.

Given
V₁=400 mL
P₁=400 mmHg
V₂=200 mL

To determine P2, rearrange the equation. Solve the equation by substituting the given values.

P₁V₁= P₂V₂

P₂= P₁V₁/V₂

P₂= (400mmHg)⋅(400mL)/200mL

P₂= 800 mmHg
