A gas originally at a pressure of 791 mm Hg and a volume of 500.0 mL is allowed to expand to 1.00 Liter. What is the new pressure of the gas? (Boyle)

The new pressure of the gas is 395.5mmHg

Explanation:

The pressure of a gas is inversely proportional to its concentration (Boyle's law). The equation that explain this law is:

P₁V₁ = P₂V₂

Where P is pressure

And V is volume of 1, initial state and 2, final state of the gas

Initial state:

791mmHg; 0.500L.

Final state:

1.00L

Replacing:

791mmHg* 0.500L = P₂*1.00L

P₂ = 395.5mmHg
