Calculating and using the van't Hoff factor for electrolytes
When 119. g of glycine (C₂H5NO₂) are dissolved in 1500. g of a certain mystery liquid X, the freezing point of the solution is 6.1 °C lower than the freezing
point of pure X. On the other hand, when 119. g of potassium bromide are dissolved in the same mass of X, the freezing point of the solution is 7.3 °C lower
than the freezing point of pure X.
Calculate the van't Hoff factor for potassium bromide in X. Be sure your answer has a unit symbol, if necessary, and round your answer to 2 significant digits.
