A mixture of ethanol and 1-propanol behaves ideally at 36 C and is in equilibrium with its vapor. If the mole fraction of ethanol in the solution is 0.63, calculate its mole fraction in the vapor phase at this temperature. (The vapor pressures of pure ethanol and 1-propanol at 36 C are 108 and 40.0 mmHg, respectively.)
