When 74.7 g of urea (CH₂N₂O). are dissolved in 900. g of a certain mystery liquid X, the freezing point of the solution is 7.7 °C lower than the freezing point of pure X. On the other hand, when 74.7 g of potassium bromide are dissolved in the same mass of X, the freezing point of the solution is 7.1 °C lower than the freezing point of pure X. Calculate the van't Hoff factor for potassium bromide in X. Be sure your answer has a unit symbol, if necessary, and round your answer to 2 significant digits. -0 i = X
