    There are three moles of oxygen in one mole of Calcium Carbonate or CaCO3.
    So in 5.79 moles of CaCO3 the number of Oxygen moles = 5.79 x 3
    in 5.79 moles of CaCO3 the number of Oxygen moles = 17.37 moles
    in one mole of Oxygen the number of atoms = 6.023 x 10^26
    in 17.37 moles of Oxygen the number of atoms=6.023 x 10^26 x 17.37
    in 17.37 moles of Oxygen the number of atoms= 1.046 x 10^28 atoms
