Formulas to find Molality

Depression in Freezing Point

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.

Symbol: ΔT_f

Measurement: TemperatureUnit: K

Note: Value can be positive or negative.

Formulas to find Depression in Freezing Point

Molal freezing point constant

Molal freezing point constant, also known as cryoscopic constant is dependent on the properties of the solvent, not the solute.

Symbol: K_f

Measurement: Cryoscopic ConstantUnit: K*kg/mol

Note: Value can be positive or negative.
