When 126. g of glycine (C₂H₂NO₂) are dissolved in 1450. g of a certain mystery liquid X, the freezing point of the solution is 3.3 °C lower than the freezing point of pure X. On the other hand, when 126. g of iron(III) chloride are dissolved in the same mass of X, the freezing point of the solution is 5.1 °C lower than the freezing point of pure X. Calculate the van't Hoff factor for iron(III) chloride in X. Be sure your answer has a unit symbol, if necessary, and round your answer to 2 significant digits.
