Question
When 153. g of glycine (C,H,NO2)
are dissolved in 1400. g of a certain mystery liquid X, the freezing point of the solution
is 4.9 °C lower than the freezing point of pure X. On the other hand, when 153. g of iron(III) nitrate (Fe(NO,)) are
dissolved in the same mass of X, the freezing point of the solution is 4.8 °C lower than the freezing point of pure X.
Calculate the van't Hoff factor for iron(III) nitrate in X. Be sure your answer has a unit symbol, if necessary, and round your
answer to 2 significant digits.
