When 33.1 g of glycine (C2H5NO2) are dissolved in 1500.g of a certain mystery liquid X, the freezing point of the solution is 2.1 e C lower than the freezing point of pure X. On the other hand, when 33.1g of ammonium chloride (NH4Cl) are dissolved in the same mass of X,thefreezingpointofthesolutionis 5.0C lower than the freezing point of pure X. Calculate the van't Hoff factor for ammonium chloride in X. Be sure your answer has a unit symbol, if necessary, and is rounded to the correct number of significant digits
