Giả sử : \(z=1\)
\(M_A=12x+y+16=74\left(\dfrac{g}{mol}\right)\)
\(\Rightarrow12x+y=58\)
\(\Rightarrow\left\{{}\begin{matrix}x=1\\y=4\end{matrix}\right.\)

Giả sử : \(z=2\)
\(M_A=12x+y+16\cdot2=74\left(\dfrac{g}{mol}\right)\)
\(\Rightarrow12x+y=42\)
\(\Rightarrow\left\{{}\begin{matrix}x=3\\y=6\end{matrix}\right.\)
