The mass of a mole of a compound is equal to the gram formula mass. In a single element, the molar mass is equal to the atomic mass multiplied by the units of grams per mol. Example A: Sulfur Molar mass=32x1g/mol=32g/mol When a molecule is made up of one kind of element, simply multiply the number of atoms of the element in each molecule by the atomic mass and then multiply by one gram per per mol. Example B: S8 molar mass= 8x32x1g/mol = 256 g/mol

Finally, if a compound is made up of multiple different elements, you simply repeat the process of finding the molar mass for one element in a compound and then add up all the different molar masses. Example C: C6H12O6 Molar Mass for C6 = 6 x 12 x 1 g/mol =72 g/mol Molar mass for H12 = 12 x 1 x 1 g/mol = 12 g/mol Molar Mass for O6 = 6 x 16 x 1 g/mol = 96 g/mol Molar Mass for C6H12O6 = 72 g/mol + 12 g/mol + 96 g/mol = 180 g/mol
