The vapor pressures of pure hexane and pure heptane at 25 °C are 151.4 mmHg and 45.62 mmHg respectively. A solution contains 0.800 mol fraction n-hexane and 0.200 mol fraction n-heptane. What is the composition of the vapor in equilibrium with this solution at 25 °C?

▸ 80.0% hexane, 20.0% heptane

▸ 50.0% hexane, 50.0% heptane

▸ 77.0% hexane, 23.0% heptane

▸ 45.0% hexane, 55.0% heptane

▸ 93.0% hexane, 7.0% heptane
