    Here is the work, and this will work with any element:

    Using the constant 6.022x10^23 for numbers of atoms per mole, we can solve using this simple equation:

    Number of atoms of element / mol constant = moles of element

    So for this it would be:

    6.73 x 10^24 atoms Cu / 6.022 x 10^23 atoms/mol

    The atoms cancel and you are left with 11.2 mol Cu
