    Number of atoms = 1.20 * 10^23

    Explanation:

    To calculate the atoms

    Let's find the number of mole

    n = m/Mm

    n = 6.40/32.065

    n = 0.1996mole

    The number of mole multiples by avogadros number

    Avogadros number = 6.02 * 10^23

    Number of atom = 0.1996 * 6.02 * 10^23

    = 1.20 * 10^23 atoms
