Calculate the vapor pressure of water for a solution of 650. g of ethylene glycol (HO-CH 2 CH 2 -OH, nonvolatile) in 1.50 kg of water at 90°C. Given the VP pure H 2 O at 90° is 525.8 mm. Moles H 2 O: 1.50 x 10 3 g x 1 mol = 83.2 mol H 2 O 18.02 g Moles EtGlyc: 650. g x 1 mol = 10.5 mol EtGlyc 62.07 g P H2O = X H2O H2O P H2O = 83. 2 mol 525.8 mm 83.2 mol + 10.5 mol P H2O = .888 525.8 mm P H2O = 457 mm
