hen 59.9 g of glycine (C₂H5NO₂) are dissolved in 850. g of a certain mystery liquid X, the freezing point of the solution is 2.9 °C lower than the freezing int of pure X. On the other hand, when 59.9 g of sodium chloride are dissolved in the same mass of X, the freezing point of the solution is 6.3 °C lower than e freezing point of pure X. alculate the van't Hoff factor for sodium chloride in X. Be sure your answer has a unit symbol, if necessary, and round your answer to 2 significant digits. i = 0 X 6

Question
When 59.9 g of glycine (C₂H5NO₂) are dissolved in 850. g of a certain mystery liquid X, the freezing point of the solution is 2.9 °C lower than the freezing point of pure X. On the other hand, when 59.9 g of sodium chloride are dissolved in the same mass of X, the freezing point of the solution is 6.3 °C lower than the freezing point of pure X. Calculate the van't Hoff factor for sodium chloride in X. Be sure your answer has a unit symbol, if necessary, and round your answer to 2 significant digits. -0 i = x10 X
