Calculating and using the van't Hoff factor for electrolytes When 76.9 g of urea (CH4N₂O) are dissolved in 650. g of a certain mystery liquid X, the freezing point of the solution is 4.00 °C less than the freezing point of pure X. Calculate the mass of ammonium chloride (NH4Cl) that must be dissolved in the same mass of X to produce the same depression in freezing point. The van't Hoff factor i = 1.80 for ammonium chloride in X. Be sure your answer has a unit symbol, if necessary, and round your answer to 3 significant digits. olo 0.0 ? 7 Ollo Ar
