Abstract:A device for measuring molarmass by freezing point depression method was improved. The results showed that the improved device is easy to operate, the experiment results is precise and could reappear. With the hexamethylene as solvent and naphthalene as solute, the relative error of molar mass of naphthalene measured is not much as 1%.
Keywords:freezing point depression  molarmass  experimental device  hexamethylene  naphthalene
