When 46.1 g of alanine (C₂H,NO₂) are dissolved in 550. g of a certain mystery liquid X, the freezing point of the solution is 6.3 °C lower than the freezing point of pure X. On the other hand, when 46.1 g of iron(III) nitrate = (Fe (NO3)3) ² are dissolved in the same mass of X, the freezing point of the solution is 7.0 °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. 0
