Question

At constant temperature, a quantity of an ideal gas occupies 50 mL at 500 mmHg pressure. At what pressure, the volume will be 100 mL?

Options

• 250 mmHg

• 1000 mmHg

• 750 mmHg

• 200 mmHg

Answer 1

250 mmHg

Explanation:

P₁V₁ = P₂V₂

∴ P₂ = `("P"_1"V"_2)/"V"_2 = (500  "mmHg" xx 50  "mL")/(100  "mL")`

= 250 mmHg
