    It isn't.

    Explanation:

    It is a counting unit for "things" - atoms, molecules, ions, etc. - and these things all have different masses.

    For example, a chemist may know that one atom of Cu reacts with one atom of S to form one molecule of CuS.

    Cu + S ⟶ CuS

    She knows that 1 mol of Cu (6.022 * 10²³ atoms of Cu) has a mass of 63.55 g and 1 mol of S (6.022 * 10²³ atoms of S) has a mass of 32.06 g.

    By measuring out 63.55 g of Cu and 32.06 g of S, she knows that there are just enough atoms of each element to react with each other.

    Thus, the mole has enabled her to count atoms.
