An ideal solution contains 40 mole % of A and 60 mole % of B at 80 degrees C. The vapor pressure of pure A and B at this temp are 480 torr and 890 torr. Calculate the vapor pressure of the solution.

  • chemistry - ,

    PA = XA*PoA.

    PB = XB*PoB.

    Ptotal = PA + PB

  • chemistry - ,

    A = 40 mole percent = 0.40 = XA
    B = 60 mole percent = 0.60 = XB
