\(MnO_2+4HCl_đ-^{t^o}\rightarrow MnCl_2+Cl_2+2H_2O\\ n_{HCl}=\dfrac{7,3}{36,5}=0,2\left(mol\right)\\TheoPT: n_{Cl_2}=\dfrac{1}{4}n_{HCl}=0,05\left(mol\right)\\ \Rightarrow V_{Cl_2}=0,05.22,4=1,12\left(l\right)\)
\(n_{HCl}=\dfrac{7,3}{36,5}=0,2(mol)\\ PTHH:MnO_2+4HCl\to MnCl_2+Cl_2+2H_2O\\ \Rightarrow n_{Cl_2}=\dfrac{1}{4}n_{HCl}=0,05(mol)\\ \Rightarrow V_{Cl_2(đkc)}=0,05.24,79=1,2395(l)\)
