At a certain temperature the vapor pressure of pure benzene is measured to be 322. torr . Suppose a solution is prepared by mixing 138.g of benzene and 91.2g of heptane .

Calculate the partial pressure of benzene vapor above this solution. 3 sig figs!

Steps/equations are appreciated...!

  • Chemistry -

    n benzene = grams/molar mass
    n heptane = grams/molar mass
    Xbenzene = n benzene/totalmols

    pbenzene = Xbenzene*Pobenzene
