\(6HCl+KClO3-->3Cl2+3H2O+KCl\)
\(n_{Cl2}=\frac{3,36}{22,4}=0,15\left(mol\right)\)
\(n_{KC_{ }LO3}=2n_{Cl2}=0,3\left(mol\right)\)
\(m=m_{KClO3}=0,3.122,5=36,75\left(g\right)\)
\(n_{Cl2}=\frac{3,36}{22,4}=0,15\left(mol\right)\)
\(KClO_3+6HCl\rightarrow KCl+3Cl_2+3H_2O\)
0,05______________0,15____________
\(\Rightarrow m_{KClO3}=0,05.122,5=6,125\left(g\right)\)
