| Video Discription | In this video we will learn how to determine molar mass of an unknown solute by using freezing point depression colligative property. you need to use the difference in the temperature of the solvent and the temperature of the solution as well as the vont hoff factor to calculate the molality. Using the molality, you need to calculate the moles of the solute in the solution.molar mass is a ratio between the mass in grams and the number of moles of solute. In this determination the depression in the freezing point of pure solvent is determined experimentally by adding known amount of the substance to known amount of a solvent.
