The Mole and Molar Mass

The Mole and Molar Mass. Remember: 1 mole = 6.02 x 10 23 particles The mass on the periodic table is correct for one atom in a.m.u. AND for 1 mole of that element in grams 6.02 x 10 23 is the number of atoms contained in the atomic masses of each element on the periodic table
