Calculate the vapor pressure at 25 ∞C of a solution containing 255 g of the nonvolatile solute, glucose, C6H12O6, in 1.50 kg of H2O. The vapor pressure of water at 25 ∞C is 23.8 mmHg. Calculate the vapor pressure at 20 ºC of a saturated solution of the nonvolatile solute, urea, CO(NH2)2, in methanol, CH3OH. The solubility is 17 g urea/100 mL methanol. The density of methanol is 0.792 g/mL, and its vapor pressure at 20 ºC is 95.7 mmHg.
