Question

In an oxidation-reduction reaction, 0.0450 mol of aqueous FeSO₄ (source of Fe²⁺) reacts completely with 120.0 mL of an acidified aqueous solution of KMnO₄ (source of MnO₄^-).
5Fe²⁺(aq) + MnO₄^-(aq) + 8H⁺(aq) → 5Fe³⁺(aq) + Mn²⁺(aq) + 4H₂O(ℓ)
What is the molarity of the KMnO₄ solution?

Provide your answer in decimal notation, rounded to the appropriate number of significant figures.
