Remember, however that 1 mole of carbon-12 = 12 grams = 6.0221367E23 atoms. It has been established that 1 mole of any element = the atomic mass of that element expressed in grams. Since magnesium has an atomic mass of 24, one mole of magnesium weighs 24 grams and contains 6.0221367E23 atoms of magnesium.

Just as one mole of carbon atoms has a mass of 12 g, ... so the mass of one mole of the atoms of any element is its "relative atomic mass" in grams. ... For example, look up the relative atomic mass of sodium (Na), (the green number above it in the periodic table). One mole of sodium has a mass of 23 g.
