When 361. g of urea (CH₂N₂O) are dissolved in 1350. g of a certain mystery liquid X, the freezing point of the solution is 8.5 °C lower than the freezing point of pure X. On the other hand, when 361. g of sodium chloride are dissolved in the same mass of X, the freezing point of the solution is 15.2 °C lower than the freezing point of pure X. Calculate the van't Hoff factor for sodium chloride in X. Be sure your answer has a unit symbol, if necessary, and round your answer to 2 significant digits.
