The formula mass of a substance is the sum of the average atomic masses of each atom represented in the chemical formula and is expressed in atomic mass units due to the use of the same reference substance in defining the atomic mass unit and the mole, the formula mass (amu) and molar mass. Analogies a mole (602 x 10 23) is a counting number like dozen (12 the roll analogy was devised to show students that calculations involving moles are similar to some they can easily do-calculations (nobody remembers the mass of an atom of an element or a formula unit of a.
