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.
