A solution is made by dissolving 26.7 g urea, a nonelectrolyte, in 301 g water. (The vapor pressure of pure water is 23.8 torr at 25°C and 71.9 torr at 45°C.)
Calculate the vapor pressure of this solution at 25°C.

mols urea = grams/molar mass = ?
mols H2O = grams/molar mass = ?
Total mols = sum
mol fraction = XH2O = mos H2O/total mols
pH2O = XH2O*PoH2O.
If you want it at 25 C, use Po at 25 C.
