. 8.00 g of a nonvolatile solute was dissolved in 200.0 g of water at 30.0 oC. The vapor pressure of the solution was measured and found to be 31.20 torr. The vapor pressure of pure water at 30.0 oC is 31.82 torr. Calculate the molar mass of the unknown solute.
3. When 7.45 grams on a nonvolatile organic compound was dissolved in 250 grams of 2- propanol, the vapor pressure was measured to be 48.58 kPa. If the vapor pressure of pure 2- propanol is 50.00 kPa at 333.75 K, what is the molar mass of the nonvolatile organic compound?
A nonvolatile, non-dissociating solute was dissolved in 12.0 g of benzene (C6H6). The freezing point of the solution was measured as 1.3 °C, while pure benzene freezes at 5.5 °C. If pure benzene has a vapor pressure of 75 torr, what is the vapor pressure of this solution. For benzene, Kf = 5.12 °C/m and Kb = 2.53 °C/m.
The vapor pressure of water is 23.76 mm Hg at 25 °C. A nonvolatile, nonelectrolyte that dissolves in water is urea. Calculate the vapor pressure of the solution at 25 °C when 6.846 grams of urea, CH4N2O (60.10 g/mol), are dissolved in 207.3 grams of water. water = H2O = 18.02 g/mol. VP(solution) = mm Hg
