Frezing point calcualtion for chem
WebThe freezing point depression is the difference between the freezing point of the pure solvent (0 °C) and the freezing point of the solution (-0.259 °C). Therefore, ΔT = 0.259 °C Step 6: Substituting these values into the equation for the freezing point depression gives: 0.259 °C = (1.86 °C/m) * (0.125 mol/kg) * 1 WebSolution Freezing Point (°C) = Solvent Freezing Point (°C) - Degrees Freezing Point is Depressed (°C) T n = T f −ΔT T n = T f − Δ T Tn is the freezing point of the solution in degrees Celsius (°C). Tf is the freezing …
