117. Solving a chemistry problem

215. Ethanol and methanol form almost ideal solutions. At 20 °C, the vapor pressure of pure ethanol is 5.933 kPa, and that of pure methanol is 11.826 kPa. Calculate: a) the molar fractions of methanol and ethanol in a solution containing 100 g of each component; b) the partial pressures of the components and the total vapor pressure over this solution; c) the mole fraction of methanol in the gas phase.
