PT: \(Zn+2HCl\rightarrow ZnCl_2+H_2\)
Ta có: \(n_{Zn}=\dfrac{13}{65}=0,2\left(mol\right)\)
Theo PT: \(\left\{{}\begin{matrix}n_{H_2}=n_{Zn}=0,2\left(mol\right)\\n_{HCl}=2n_{Zn}=0,4\left(mol\right)\end{matrix}\right.\)
\(\Rightarrow V_{H_2}=0,2.22,4=4,48\left(l\right)\)
\(C_{M_{HCl}}=\dfrac{0,4}{0,2}=2\left(M\right)\)
