Name Section Experiment 16 Depression Date Determination of the Molar Mass of a Compound from Freezing om Postlaboratory Questions 1. 1.5445 g benzoic acid (122.13 g/mole) is dissolved in 11.933 g of lauric acid. At what temperature will the solution freeze? Kf-3.9°C/m Tr= 44.0°C A solution was made by dissolving 0.352 g of a solute in 25.3 g of water. The freezing point was-1.01°C. What is the molar mass of the solute? 2. Kf= 1.856°C/m 25
