Gọi \(\left\{{}\begin{matrix}Al:x\left(mol\right)\\Fe:y\left(mol\right)\end{matrix}\right.\)
\(n_{H_2}=\dfrac{9,6}{22,4}=\dfrac{3}{7}mol\)
\(2Al+6HCl\rightarrow2AlCl_3+3H_2\uparrow\)
\(Fe+2HCl\rightarrow FeCl_2+H_2\uparrow\)
\(\Rightarrow\left\{{}\begin{matrix}1,5x+y=\dfrac{3}{7}\\27x+56t=11\end{matrix}\right.\Rightarrow\left\{{}\begin{matrix}x=\dfrac{13}{57}\\y=\dfrac{23}{266}\end{matrix}\right.\)
\(\%m_{Al}=\dfrac{\dfrac{13}{57}\cdot27}{11}\cdot100\%=55,98\%\)
\(\%m_{Fe}=100\%-55,98\%=44,02\%\)
\(m_{AlCl_3}=\dfrac{13}{57}\cdot133,5=30,45g\)
\(m_{FeCl_2}=\dfrac{23}{266}\cdot127=10,98g\)
