Question

50 cm³ of hydrogen is collected over water at 17°C and 750 mm Hg pressure. Calculate the volume of dry gas at S.T.P. The water vapour pressure at 17°C is 14 mm Hg.

KnowledgeBoat · Accepted Answer

Initial conditions : P₁ = 750 - water vapour pressure = 750 - 14 = 736 mm Hg V₁ = Initial volume of the gas = 50 cm³ T₁ = Initial temperature of the gas = 17°C = 17 + 273 = 290 K Final conditions : P₂ (Final pressure) = 760 mm of Hg T₂ (Final temperature) = 273 K V₂ (Final volume) = ? By Gas Law: Substituting the values : ∴ Volume of dry gas = 45.6 cm³
