(A) The chemical formula of barium carbonate is $BaCO_3$.In $1$ mole of $BaCO_3$,there are $3$ moles of oxygen atoms.Therefore,to find the number of moles of $BaCO_3$ containing $1.5$ moles of oxygen atoms,we use the unitary method:$	ext{Moles of } BaCO_3 = \frac{1 	ext{ mole of } BaCO_3}{3 	ext{ moles of } O} 	imes 1.5 	ext{ moles of } O = 0.5 	ext{ moles}$.

The number of moles of $BaCO_3$ which contain $1.5$ moles of oxygen atoms is:
