a) \(n_{HCl}=0,5.1,6=0,8\left(mol\right)\)
PTHH: Zn + 2HCl → ZnCl2 + H2
Mol: x 2x x x
PTHH: 2Al + 6HCl → 2AlCl3 + 3H2
Mol: y 3y y 1,5y
Ta có: \(\left\{{}\begin{matrix}65x+27y=11,9\\2x+3y=0,8\end{matrix}\right.\Leftrightarrow\left\{{}\begin{matrix}x=0,1\\y=0,2\end{matrix}\right.\)
\(\Rightarrow V_{H_2}=\left(0,1+1,5.0,2\right).22,4=8,96\left(l\right)\)
b, \(m_{muối}=0,1.136+0,2.133,5=40,3\left(g\right)\)
