In the laboratory, cryoscopy is sometimes used to estimate the molecular mass of a new substance, and this also relies on freezing point depression. Hence, the addition of solute molecules lowers the vapor pressure of the solution, which in turn lowers the freezing point of a solution, and this is known as depression in the freezing point of a solution.
