Calculate the mass of ethylene glycol c2h6o2 that must be, Ask an Expert

Academics

A) Calculate the vapor pressure of water above a solution prepared by dissolving 33.0 g of glycerin (C3H8O3) in 125 g of water at 343 K. (The vapor pressure of water at 343 K 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 12.0 torr at 35C. The vapor pressure of pure ethanol at 35C is 1.00x10^2 torr.
