\(n_X=0,09\left(mol\right)\)
\(n_{\text{Khí dư}}=n_{ankan}=0,07\left(mol\right)\)
\(\Rightarrow n_{ankan}=0,02\left(mol\right)\)
Mà:
\(n_{ankan}=n_{anken}\)
\(\Rightarrow\frac{Mankan}{Manken}=\frac{2}{7}\)
+ Ta thấy chỉ có cặp:\(\left\{{}\begin{matrix}CH4\\C4H8\end{matrix}\right.\text{Là phù hợp}\)
