P=101.32 kPaPolyethylene glycol 400 (PEG400) is a nonvolatile liquid polymer, which when mixed with water canbe used as a base for parenteral formulations. The designation “400” means that the molecular weightof PEG molecules is approximately 400 g/mol. Preparation with water (ΔHv = 40.7 kJ/mol) requires that the two be mixed at 56 oC, at which the equilibrium vapor pressure of pure water is 16.5 kPa. a. If 105 g of PEG400 are added to 500 g of water at 56 oC, what will the boiling temperature of the solution be?
