When 73.6 g of glycine C2H5NO2 are dissolved in 1250. g of a certain mystery liquid X, the freezing point of the solution is 2.8°C lower than the freezing point of pure X. On the other hand, when 73.6 g of potassium bromide are dissolved in the same mass of X, the freezing point of the solution is 2.6°C lower than the freezing point of pure X. Calculate the van't Hoff factor for potassium bromide in X.
