When 20.4 g of urea (CH₂N₂O) are dissolved in 500. g of a certain mystery liquid X, the freezing point of the solution is 4.3 °C lower than the freezing point of pure X. On the other hand, when 20.4 g of iron(III) chloride are dissolved in the same mass of X, the freezing point of the solution is 5.2 °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 is rounded to the correct number of significant digits. X
