Igcse Model Questions Vol1 2020 Chemistry Question 27
Practice objective / multiple choice question 27 from the 2020 Igcse Model Questions Vol1 Chemistry examination.
A sealed 5.00 L container initially contains dry air at \(25^{\circ}\text{C}\) and a pressure of \(1.00\ \text{atm}\). Water is then introduced and the container is heated to \(35^{\circ}\text{C}\). The vapour pressure of water at \(35^{\circ}\text{C}\) is \(0.056\ \text{atm}\). Assuming ideal‑gas behaviour, calculate the mole fraction of water vapour in the final gas mixture.
