solution is made by adding 0.100 mole of ethyl ether to 0.350 mole of ethyl alcohol. If the vapor pressure of ethyl ether and ethyl alcohol at 20°C are 375 torr and 20.0 torr, respectively, the vapor pressure of the solution at 20°C (assuming ideal behavior) is:

    Pether = Xether*Po ether
    Palc = Xalc*Po alc

    Ptotal = pether + palc

    I assume you know how to get Xether and Xalc. Xether = mols ether/total mols.
    Xalc = mols alc/total mols.
