How Many Atoms Of Oxygen Are There In 5.79moles Of Calcium Carbonate?

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
