    Mole = No. Of atom/Avogadro const

    Avogadro constant = 6.02*10^23

    Mass of Cu = 22g

    Molar mass of Cu = 63.5g/mol

    Mole = mass/molar mass

    Mole = 22/63.5

    Mole = 0.346

    No. Of atom=mloe * avogadro conts

    No. Of atom = 0.346 * 6.02*10^23

    No. Of atom = 2.09 * 10^23atoms
