### How is the mass of an atom related to its mole?

• The mass of an atom in amu is numerically the same as the mass of one mole of atoms of the element in grams. • One atom of sulfur has a mass of 32.07 amu; one mole of S atoms has a mass of 32.07 g. Mass of 1 H atom: 1.008 amu x 1.661 x10-24 g/amu = 1.674 x10-24 g Mass of 1 mole of H atoms: 1.674 x10-24g/H atom x 6.022 x1023H atoms = 1.008 g
