What is the composition of a methanol () – propanol () solution that has a vapor pressure of 121 torr at 40°C? At 40°C, the vapor pressures of pure methanol and pure propanol are 303 and 44.6 torr, respectively. Assume the solution is ideal.

Question

Mole fraction of methanol =

Mole fraction of propanol =
