question

A 50 mole % solution ofpropylalcohol and ethyl alcohol is distilled to the boiling point of 90°C. The vapor pressure of the condensate collected in a cooled receiver is 1066 mm Hg at that temperature. The vapor pressure of pure ethyl andpropylalcohols are 1190 and 574 mm Hg respectively, at 90°C. Calculate a) the mole fraction of ethyl alcohol in the boiling liquid; b) the mole fraction of ethyl alcohol in the distillate; c) the number of moles of ethyl alcohol that were distilled. Assume ideal behavior of the solution and the vapors.
