For (I), three moles of CO contain 3 moles of C atoms and 3 moles of O atoms, totaling 6 moles of atoms. For (II), two moles of COS (assuming ₂ is a typographical error and meant to represent COS) contain 2 moles of C atoms, 2 moles of O atoms, and 2 moles of S atoms, also totaling 6 moles of atoms. Therefore, both (I) and (II) have the same number of atoms, making them equal.
