The vapor pressure of carbon tetrachloride CCl4, , is 0.354atm and the vapor pressure of chloroform, CHCl3, is 0.526atm at 316K. A solution is prepared from equal masses of these two compounds at this temperature.

a) Calculate the mole fraction of the chloroform in the vapor above the solution.

I would like a hint. Not the solution please.

Find number of moles of each if you mix say x grams of each.(x will cancel in mole fraction). I suppose you know raoults law....
