[answerhappygod]

When 386. g of glycine C2H5NO2 are dissolved in 1500. g of acertain mystery liquid X, the freezing point of the solution is 8.8°C lower than the freezing point of pure X. On the other hand, when386. g of iron(III) chloride are dissolved in the same mass of X,the freezing point of the solution is 13.5°C lower than thefreezing point of pure X. Calculate the van't Hoff factor foriron(III) chloride in X. Be sure your answer has a unit symbol, ifnecessary, and round your answer to 2 significant digits.
