A. Calculate the vapor pressure of water above a solution prepared by dissolving 26.9 g of glycerin (C3H8O3) in 183 g of water at 343 K. Vapor Pressure (torr) at 343 (or 70) is 233.7 torr
B. Calculate the mass of ethylene glycol (C2H6O2) that must be added to 1.00 kg of ethanol (C2H5OH) to reduce its vapor pressure by 13.6 torr at 35°C. The vapor pressure of pure ethanol at 35°C is 1.00 102 torr.
