A solution is made by mixing methanol (CH3OH, Po=94.0torr) and ethanol (CH3CH2OH,
Po=44.0torr) at a constant 20.0oC.
a) Determine the mole fraction of methanol and ethanol in a solution made from 75.0g of
each liquid.
b) Determine the vapor pressure of methanol and ethanol produced by this solution. What
is the total pressure contributed by the solution?
c) If you wanted to separate these two solutions by distillation, which of the two liquids
would you collect from vapor and which would remain a liquid?
