Answer to Question #118928 in General Chemistry for timea

Question

a fixed quantity of gas is compressed at constant tempature from a volume of 638 mL to 208 mL. if the initial pressure was 522 mm Hg, what is the final pressure?

Answer 1

Solution: According to law Mendeleev-Clapeyron at constant temperature: P₁V₁=P₂V₂. We known that P₁=522 mm Hg and V₁=638 mL are inital units, and V₂=208 mL is a final volume, then P₂=P₁V₁/V₂=522*638/208=1601 mm Hg is the final pressure

Answer: 1601 mm Hg.
