Freezing Point Calculator

Enter the freezing point depression constant and the molality into the calculator to determine the freezing point of the liquid.

Freezing Point Formula

The following equation is used to calculate the freezing point of a liquid.

T = Kf * m

  • Where T is the freezing point
  • Kf is the freezing point depression constant
  • m is the molality

Freezing Point Definition

A freezing point is the temperature at which a liquid transitions to a solid.

Freezing Point Example

How to calculate a freezing point?

  1. First, determine the the freezing point depression.

    Determine the constant of freezing point depression.

  2. Next, determine the molality.

    Measure the molality.

  3. Finally, calculate the freezing point.

    Calculate the freezing point using the formula.


What is a freezing point?

A freezing point is a specific temperature in which a liquid begins to transition to a solid.

What is a freezing point depression constant?

The depression constant is a measure of energy required to keep a solution in a liquid state.

What is molality?

Molality is a measure of moles of solute per kilogram of solvent.
