$\mathrm{K}\mathrm{M}\mathrm{n}{\mathrm{O}}_4$(mol. wt. = 158) oxidizes oxalic acid in acidic medium to$\mathrm{C}{\mathrm{O}}_2$and water as follows
$5{\mathrm{C}}_2{\mathrm{O}}_4^{2-}+2\mathrm{M}\mathrm{n}{\mathrm{O}}_4^{-}+16{\mathrm{H}}^{+}\to 10\mathrm{C}{\mathrm{O}}_2+2\mathrm{M}{\mathrm{n}}^{2+}+8{\mathrm{H}}_2\mathrm{O}$
What is the equivalent weight of$\mathrm{K}\mathrm{M}\mathrm{n}{\mathrm{O}}_4$?
