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

The vapor pressures of pure hexane and pure heptane at 25 °C are 151.4 mmHg and 45.62 mmHg respectively. An ideal solution contains 0.700 mol fraction hexane and 0.300 mol fraction heptane. What is the composition of the vapor in equilibrium with this solution at 25 °C?
