Question

A gas sample occupies 350.0 mL at 546 mm Hg. What volume does the gas occupy at 652 mm Hg?​

Answer 1

293.1 mL.

Step-by-step explanation:

• Boyle's law states that: at a constant temperature the pressure of a given mass of an ideal gas is inversely proportional to its volume.

• It can be expressed as: P₁V₁ = P₂V₂,

P₁ = 546.0 mm Hg, V₁ = 350.0 mL.

P₂ = 652.0 mm Hg, V₂ = ??? mL.

∴ V₂ = (P₁V₁)/(P₂) = (546.0 mm Hg)(350.0 mL) / (652.0 mm Hg) = 293.1 mL.
