Gce Model Questions Vol1 2020 Chemistry Question 7
Practice objective / multiple choice question 7 from the 2020 Gce Model Questions Vol1 Chemistry examination.
At 30 °C the vapour pressures of n‑pentane (\(\ce{C5H12}\)) and isopentane (\(\ce{2‑methylbutane}\)) are 0.45 atm and 0.60 atm respectively. A liquid mixture of these two hydrocarbons exerts a total vapour pressure of 0.525 atm at the same temperature. Assuming the mixture behaves ideally, calculate the mole fraction of n‑pentane in the liquid phase.
