PLEASE SHOW ALL FORMULAS AND DETAILED WORK. THANKS.
Part A
Calculate the vapor pressure of water above a solution prepared by dissolving 28.0 g of glycerin (C3H8O3) in 145 g of water at 343 K. (The vapor pressure of water at 343 K is 233.7 torr.)
PH2O = torr

Part 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 9.00 torr at 35âC. The vapor pressure of pure ethanol at 35âC is 1.00Ã102 torr.
