A solution is made by dissolving 29.7 g urea (CH4N2O), a nonelectrolyte, in 275 g water. Calculate the vapor pressure of this solution at 25°C and 45°C.

The vapor pressure of diethyl ether (ether) is 463.57 mm Hg at 25 °C. A nonvolatile, nonelectrolyte that dissolves in diethyl ether is aspirin.Calculate the vapor pressure of the solution at 25 °C when 10.17 grams of aspirin, C9H8O4 (180.1 g/mol), are dissolved in 151.7 grams of diethyl ether.diethyl ether = CH3CH2OCH2CH3 = 74.12 g/mol.           The vapor pressure of diethyl ether (ether) is 463.57 mm Hg at 25°C.How many grams of estrogen (estradiol), C18H24O2, a nonvolatile, nonelectrolyte (MW = 272.4 g/mol), must be added to 192.1 grams of diethyl ether to reduce the vapor pressure to 452.63 mm Hg ?diethyl ether = CH3CH2OCH2CH3 = 74.12 g/mol.

The vapor pressure of chloroform is 173.11 mm Hg at 25 °C. A nonvolatile, nonelectrolyte that dissolves in chloroform is aspirin.Calculate the vapor pressure of the solution at 25 °C when 13.35 grams of aspirin, C9H8O4 (180.1 g/mol), are dissolved in 238.1 grams of chloroform.chloroform = CHCl3 = 119.40 g/mol.VP(solution) =  __________mm Hg

Consider naphthalene, C10H8. A solution of naphthalene is prepared by mixing 25.0g of naphthalene with 0.750 L of carbon disulfide CS2(density=1.263g/mL). Assume that the volume of the solution is the same as that of the solvent after the solution is prepared. The vapor pressure of pure CS2 at 25 degrees Celsius is 358 mm Hg. Calculate the vapor pressure of this solution at this temperature.
