A 1.24-M solution of KI has a density of 1.15 g/cm3.
a) Calculate the mole fraction of water in this solution, assumingthat the KI is completely dissociated.
b) Predict the vapor pressure of water over this solution at25°C, assuming complete dissociation of the KI.
c) Predict the freezing point of this solution, assuming completedissociation of the KI.
d) The freezing point of this solution is measured to be-4.46°C. What percent of the KI is actually dissociatedin this solution?
