    Answer: The number of atoms = 2.20*10^24

    Explanation:

    From stoichiometry relations;

    Mole =

    Number of particles / Avogadro's constanst

    Particles may be atoms, molecules or ions

    Avogadro's constant is the number of atoms in a mole = 6.02*10^23

    3.66 = Number of atoms / 6.02*10^23

    Number of atoms = 3.66*6.02*10^23

    Number of atoms = 2.20*10^24

    Therefore the number of atoms present is

    2.20*10^24
