For the reaction,

FeS2+KMnO4+H∗⟶Fe3++H2SO4+Mn2++H2O\mathrm{FeS}_2+\mathrm{KMnO}_4+\mathrm{H}^* \longrightarrow \mathrm{Fe}^{3+}+\mathrm{H}_2 \mathrm{SO}_4+\mathrm{Mn}^{2+}+\mathrm{H}_2 \mathrm{O}

if the molar mass of FeS2\mathrm{FeS}_2 is M\mathrm{M}, then equivalent mass of FeS2\mathrm{FeS}_2 would be equal to
View answer and explanation
Correct option: D
M15\frac{M}{15}
Option D (M/15) is correct because the equivalent mass is the molar mass divided by the change in oxidation state of FeS2, which is 15.
