Gọi: \(\left\{{}\begin{matrix}n_C=x\left(mol\right)\\n_S=y\left(mol\right)\end{matrix}\right.\)
⇒ 12x + 32y = 13,5 (1)
PT: \(C+O_2\underrightarrow{t^o}CO_2\)
\(S+O_2\underrightarrow{t^o}SO_2\)
Theo PT: \(\left\{{}\begin{matrix}n_{CO_2}=n_C=x\left(mol\right)\\n_{SO_2}=n_S=y\left(mol\right)\end{matrix}\right.\)
Mà: \(n_{hhk}=\dfrac{11,2}{22,4}=0,5\left(mol\right)\)
⇒ x + y = 0,5 (2)
Từ (1) và (2) \(\Rightarrow\left\{{}\begin{matrix}x=0,125\left(mol\right)\\y=0,375\left(mol\right)\end{matrix}\right.\)
\(\Rightarrow\left\{{}\begin{matrix}m_{C=}0,125.12=1,5\left(g\right)\\m_S=0,375.32=12\left(g\right)\end{matrix}\right.\)
