PTHH: \(Zn+2HCl\rightarrow ZnCl_2+H_2\left(1\right)\)
\(2Al+6HCl\rightarrow2AlCl_3+3H_2\left(2\right)\)
Theo PT (1): \(n_{H_2}=n_{Zn}=\frac{1,3}{65}=0,02\left(mol\right)\)
Theo PT (2)\(n_{H_2}=\frac{3}{2}n_{Al}=\frac{3}{2}.\frac{2,7}{27}=0,15\left(mol\right)\)
\(\Rightarrow V_{H_2}=\left(0,02+0,15\right).22,4=3,808\left(l\right)\)
