(B) The chemical formula of ammonium phosphate is $(NH_4)_3PO_4$.In one mole of $(NH_4)_3PO_4$,there are $12$ moles of hydrogen atoms $(3 	imes 4 = 12)$ and $4$ moles of oxygen atoms.Let $n_H$ be the moles of hydrogen atoms and $n_O$ be the moles of oxygen atoms.The ratio of moles of hydrogen atoms to oxygen atoms is $\frac{n_H}{n_O} = \frac{12}{4} = 3$.Given that $n_H = 6$ moles,we have $\frac{6}{n_O} = 3$.Therefore,$n_O = \frac{6}{3} = 2$ moles.

$A$ sample of ammonium phosphate,$(NH_4)_3PO_4$,contains $6$ moles of hydrogen atoms. The number of moles of oxygen atoms in the sample is:
