Mole of complex$=\frac{\mathrm{W}}{\mathrm{m}\mathrm{o}\mathrm{l}.\text{wt.}}=\frac{1}{266.5}$
1 mole of complex produces 2 mole HCl
${\text{[Cr(H}}_{\text{2}}{\text{O)}}_{\text{5}}{\text{Cl]Cl}}_{\text{2}}\to {\text{Cr(H}}_{\text{2}}{\text{O)Cl]}}^{\text{2+}}{\text{2Cl}}^{\text{–}}$
Mole of HCl formed$=\frac{1}{266.5}\times 2$
${\text{N}}_{\text{HCl}}\text{=}\frac{\text{n}}{\text{V}}\text{×}\text{n}-\text{factor}\text{=}\frac{\text{2}}{\text{266}\text{.5×1}}$
$\text{=}\text{7}\text{.5}\text{×}{\text{10}}^{\text{–3}}\text{N}$
