Pure ethylene glycol, HOCCH2CH2OH, is added to 2.0kg of water in the cooling system of a car. The vapor pressure of the solution in the system when the temperature is 90oC is 457 mm Hg. What mass of glycol was added? (Assume the solution is ideal)
The vapor pressure of water at STP in an ideal solution is 525.8 mm Hg at 90oC.
