Question

Pentane, C5H12, and hexane, C6H14, combine to form an ideal solution. At 25⁰C the vapor pressure of pentane is 511 torr and that of hexane is 150 torr. In the vapor over a pentane-hexane solution at 25⁰C, the mole fraction of pentane is 0.15. What is the mole fraction of pentane in the solution?
