$0.1\mathrm{\hspace{0.33em}}\mathrm{M}$$\mathrm{K}\mathrm{M}\mathrm{n}{\mathrm{O}}_4$is used for following titration. What volume of the solution in$\mathrm{mL}$will be required to react with$0.158\mathrm{\hspace{0.33em}}\mathrm{g}$of${\mathrm{N}\mathrm{a}}_2{\mathrm{S}}_2{\mathrm{O}}_3$?
Not balanced:${\mathrm{S}}_2{\mathrm{O}}_3^{2-}+\mathrm{M}\mathrm{n}{\mathrm{O}}_4^{-}+{\mathrm{H}}_2\mathrm{O}\to \mathrm{M}\mathrm{n}{\mathrm{O}}_{2(\mathrm{s})}+\mathrm{S}{\mathrm{O}}_4^{2-}+\mathrm{O}{\mathrm{H}}^{-}$
