    To determine the number of zinc atoms from a given mass of zinc metal, we need to convert the mass into moles by using the atomic mass of zinc which is 65.38 grams per mole. Then, we use the Avogadro's number to convert it to number of atoms. It represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. We do as follows:

    Moles Zn = 922 g (1 mol / 65.38 g) = 14.10 mol

    no. of Zn atoms = 14.10 mol Zn (6.022 x 10^23 atoms / mole) = 8.49x10^24 atoms Zn
