When 131. g of glycine (C2H5NO2)
are dissolved in 1350. g of a certain mystery liquid X, the freezing point of the solution is 2.00 °C less than the freezing
point of pure X.
Calculate the mass of iron(III) nitrate (Fe(NO,),) that must be dissolved in the same mass of X to produce the same depression in freezing point. The van't
Hoff factor i=3.04 for iron(III) nitrate in X.
Be sure your answer has a unit symbol, if necessary, and round your answer to 3 significant digits.
