STEP 0: Pre-Calculation Summary

Formula Used

Cryoscopic Constant = Depression in Freezing Point/(Van't Hoff Factor*Molality)
k_f = ΔT_f/(i*m)
This formula uses 4 Variables

Variables Used

Cryoscopic Constant - (Measured in Kelvin Kilogram per Mole) - The Cryoscopic Constant is described as the freezing point depression when a mole of non-volatile solute is dissolved in one kg of solvent.
Depression in Freezing Point - (Measured in Kelvin) - The Depression in Freezing Point is the phenomena that describes why adding a solute to a solvent results in the lowering of the freezing point of the solvent.
Van't Hoff Factor - A Van't Hoff Factor is the ratio of observed colligative property to theoretical colligative property.
Molality - (Measured in Mole per Kilogram) - Molality is defined as the total number of moles of solute per kilograms of solvent present in the solution.

STEP 1: Convert Input(s) to Base Unit

Depression in Freezing Point: 12 Kelvin --> 12 Kelvin No Conversion Required
Van't Hoff Factor: 1.008 --> No Conversion Required
Molality: 1.79 Mole per Kilogram --> 1.79 Mole per Kilogram No Conversion Required
