\(PTHH:2Al+6HCl\rightarrow2AlCl_3+3H_2\)
Ta có:
\(n_{Al}=\frac{5,4}{27}=0,2\left(mol\right)\)
\(\Rightarrow n_{H2}=\frac{3}{2}n_{Al}=0,3\left(mol\right)\)
\(\Rightarrow V_{H2}=0,3.22,4=6,72\left(l\right)\)
\(n_{AlCl3}=n_{Al}=0,2\left(mol\right)\)
\(\Rightarrow m_{AlCl3}=0,2.133,5=26,7\left(g\right)\)
