A solution contains naphthalene(C10H8) dissolved in hexane (C6H14) at a concentration of 14.52 % naphthalene by mass.Calculate the vapor pressure at 25 degrees C of hexane above the solution. The vapor pressure of pure hexane at 25 degrees C is 151 .

    Psolution = Xhexane*Pohexane

    14.52% by mass = 14.52g naphthalene dissolved in 14.52 g naphthalene+85.48 g hexane.
    Convert 14.52 g naphthalene to moles.
    Convert 85.48 g hexane to moles.
    mole fraction hexane = moles hexane/total moles.
