A soluation of HO-CH2-CH2-OH is prepared by dissolving 651g of ethylene gylcol in 1.50kg of water. Determine the freezing point of the soluaiton and the vapor pressure of water above the solution 25.0 degrees C. The normal freezing point of water is water is 0.00 degrees C with a freezing oint depression constant of 1.86 degrees C/m, and the vapor pressure of pure water at 25.0 degees C is 23.8 torr.
