If 0.500 mol of a nonvolatile nonelectrolyte are dissolved in 3.70 mol of water, what is the vapor pressure PH2O of the resulting solution? the vapor pressure of pure water is 23.8 torr at 25 degree C.
A solution is composed of 1.30 mol cyclohexane (Pcy=97.6 torr) and 2.50 mol acetone (Pac=229.5 torr). what is the total vapor pressure Ptotal above this solution?
