At temperature 63.50 °c, the vapour pressures of pure h20 and pure ethanol, c2h5oh
are 175.00 and 4.00 x 102 torr, respectively. a solution is prepared by mixing equal masses
of h20 and c2h5oh.
a) calculate the mole fraction of ethanol in the solution.
b) what is the vapour pressure of the solution at 63.50 °c?
c) determine the mole fraction of ethanol in the vapour phase above the solution.
( 0.28, 238.20 torr, 0.47)
