7 8. When 70.2 g of glycine (C, H,NO,) are dissolved in 900. g of a certain mystery liquid X, the freezing point of the solution is 3.7 °C lower than the freezing point of pure X. On the other hand, when 70.2 g of ammonium chloride (NH, Cl) are dissolved in the same mass of X, the freezing point of the solution is 9.0 °C lower than the freezing point of pure X. Calculate the van't Hoff factor for ammonium chloride in X. Be sure your answer has a unit symbol, if necessary, and round your answer to 2 significant digits. i= 1 Submit Assignment Continue Accessibility O 2022 McGraw Hill LLC. All Rights Reserved.

At a certain temperature the vapor pressure of pure acetyl bromide (CH,COBr) is measured to be 0.46 atm. Suppose a solution is prepared by mixing 71.6 g of acetyl bromide and 97.6 g of heptane (C,H,16): Calculate the partial pressure of acetyl bromide vapor above this solution. Be sure your answer has the correct number of significant digits. Note for advanced students: you may assume the solution is ideal. atm x10
