The vapor pressure of benzene is 73.03 mm Hg at 25°C.How many grams of testosterone, C19H28O2, a nonvolatile, nonelectrolyte (MW = 288.4 g/mol), must be added to 263.1 grams of benzene to reduce the vapor pressure to 70.87 mm Hg?benzene = C6H6 = 78.12 g/mol._______g testosterone

The vapor pressure of pure toluene (C6H5CH3, MW = 92.14 g/mol) at T = 100.0 °C is pT° = 557.0 torr.  What is the vapor pressure of a solution containing 20.00 g of naphthalene (C10H8, MW = 128.17 g/mol), a nonvolatile solute, and 240.0 g of toluene, at T = 100.0 °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.

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.
