Freezing point change formula

WebExperimentally, we know that the change in freezing point of the solvent in a solution from that of the pure solvent is directly proportional to the molal concentration of the solute: T = Kfm where: T is the change in freezing … WebFreezing point depression is calculated using the equation: Each of these solutions has a different molality, which needs to be calculated. Molality is equal to moles of solute per kilogram solvent. To find this value, convert grams to moles (using molar mass) and divide by the mass of the solvent.
