A solution contains 5.0 g of a non-electrolyte solute with a molar mass of 121 g/mol dissolved in 95.4 g of chloroform. The solution has a freezing point of -65.8°C. The freezing point of pure chloroform is -63.5°C. What is the freezing point constant, kf, for this solvent? Part A: How many moles of solute are present in the solution? Part B: How many kg of chloroform are present in the solution? Part C: What is the molality, m, of the solution? Part D: What is the change in freezing point, ATf, for the solvent? Part E: What is the freezing point constant, kf, for this solvent? A solution contains 5.0 g of a non-electrolyte solute with a molar mass of 121 g/mol dissolved in 95.4 g of chloroform.
