When 109.0 g of glycine C2H5NO2 are dissolved in 1050.0 g of a certain mystery liquid X, the freezing point of the solution is 6.1 °C lower than the freezing point of pure X. On the other hand, when 109.0 g of sodium chloride are dissolved in the same mass of X, the freezing point of the solution is 11.9 °C lower than the freezing point of pure X.
Calculate the van't Hoff factor for sodium chloride in X.
