When 86.7 g of urea (CH, N,O) are dissolved in 1400. g of a certain mystery liquid X, the freezing point of the solution is 8.70 C less than the freezing point of pure X. Calculate the mass of sodium chloride 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 sodium chloride in X. Be sure your answer has a unit symbol, if necessary, and round your answer to 3 significant digits.
