WebQuestion #218707. Calculate the freezing point and boiling point in each solution, assuming complete dissociation of the solute. a. 10.5 g FeCl3 in 1.50 * 102 g water. Expert's answer. We Consider aqueous of FeCl3 . Depression in freezing point = i . Kf . m. Elevation in Boilling point = i . WebΔTf = (1.86 C/m) × (0.6 m) × 3 = 3.348 C. The freezing point depression is the difference between the freezing point of pure water (0°C) and the freezing point of the solution: Freezing point of solution = 0 ° C − Δ T f = 0 ° C − 3.348 ° C = − 3.348 ° C. Therefore, the freezing point of the solution is -3.348°C. potton house priory group
