The freezing point of 0.251 m urea in water is to be calculated. Concept introduction: The freezing point is the temperature at which both the solid and liquid phases coexist in equilibrium. It is the temperature at which the vapor pressure of the substance in the liquid state becomes equal to the vapor pressure in a solid state. It is a colligative property because it depends on the number of moles of solute particles that are present in the substance.
