The relations among amount of substance (in moles), mass (in grams), and number of chemical entities The freezing point apparatus consists of a freezing point test tube fitted with a stopper, a digital thermometer and a stirring wire. The molar mass of I 2 is 253.809 and the molar mass of the unknown is x 1 / 4.25 = x / 253.809. n = Mass /Molar Mass. • Molar mass has units of grams per mole (g/mol). 2Al + I2 —>Al2I6. The molar mass of i2 is 253.80 g/mol, and the molar mass of ni3 is 394.71 g/mol. Molar mass of AlI3 = 407.694948 g/mol. Previous.
