\(2Al+6HCl\rightarrow2AlCl_3+3H_2\)
\(n_{Al}=\dfrac{5,4}{27}=0,2\left(mol\right)\)
Theo PTHH: \(n_{AlCl_3}=n_{Al}=0,2\left(mol\right)\)
\(\Rightarrow m_{AlCl_3}=0,2.133,5=26,7\left(g\right)\)
Theo PTHH: \(n_{H_2}=\dfrac{0,2.3}{2}=0,3\left(mol\right)\)
\(\Rightarrow V_{H_2}=0,3.22,4=6,72\left(l\right)\)
