Molality given Freezing Point Depression Solution

STEP 0: Pre-Calculation Summary

Formula Used

Molality = Depression in Freezing Point/Molal freezing point constant
m = ΔT_f/K_f
This formula uses 3 Variables

Variables Used

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.
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.
Molal freezing point constant - (Measured in Kelvin Kilogram per Mole) - Molal freezing point constant, also known as cryoscopic constant is dependent on the properties of the solvent, not the solute.

STEP 1: Convert Input(s) to Base Unit

Depression in Freezing Point: 12 Kelvin --> 12 Kelvin No Conversion Required
Molal freezing point constant: 100 Kelvin Kilogram per Mole --> 100 Kelvin Kilogram per Mole No Conversion Required

Explain Freezing Point Depression.

The Freezing point depression is the temperature at which the liquid solvent and solid solvent are at equilibrium so that their vapor pressures are equal. When a non-volatile solute is added to a volatile liquid solvent, the solution vapor pressure will be lower than that of the pure solvent. As a result, the solid will reach equilibrium with the solution at a lower temperature than with the pure solvent.
