Molar mass tells us the mass of 1 mol of an atom or compound. In each case we simply calculate the sum of the masses of the atoms in the formula to determine the mass of a mole. These masses can be found on the periodic table. EXAMPLE: Calculate the molar mass of a mole of iodine, I 2. Use all numbers from the periodic table.
