When 72.8 g of alanine (C₂H-NO₂) are dissolved in 1450. g of a certain mystery liquid X, the freezing point of the solution is 7.90 °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=1.74 for ammonium chloride in X. Be sure your answer has a unit symbol, if necessary, and round your answer to 3 significant digits.
