Molar mass (formula mass/ grams): The sum of the atomic masses of all the atoms in a molecule. The number of grams you need to make one mole of atoms of an element is equal to the atomic mass of the element. Avogadro’s number: the number of representative particles contained in one mole of a substance. 1 pair = 2. 1 dozen = 12. 1 mole = 6.02x1023
