Academics

(a) Calculate the vapor pressure of water above a solution prepared by dissolving 38.7 g in glycerin (C3H8O3) to 155 g of water at 343 K. (The vapor pressure of water is given in Appendix B.) 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 14.2 torr at 35°C. The vapor pressure of pure ethanol at 35°C is 1.00 x102 torr.
