Answer to Question #319253 in General Chemistry for Karolyn

Question

A sample of oxygen gas occupies a volume of 7.93 L at 59 °C and 843 mm Hg. The volume of the gas sample increases to 8.96 L while its pressure increases to 1.13 x 10^3 mm Hg. If the ideal gas law is obeyed, the temperature of the gas sample at the new volume and pressure is _____ °C.

Answer 1

p₁V₁/T₁ = p₂V₂/T₂

T₂ = p₂V₂T₁/p₁V₁ = (8.96 L)×(1.13×10³ mm Hg)×(59 + 273.15 K) / (7.93 L)×(843 mm Hg) = 503 K or 230°C
