In a Reaction Between XeO₃(aq)and Mn²⁺(aq)that Occurred in 324 ML

Multiple Choice

In a reaction between XeO₃(aq) and Mn²⁺(aq) that occurred in 324 mL of aqueous solution,the gaseous Xe produced occupied a volume of 595 mL at STP.What is the molarity of the MnO₄^-(aq) solution resulting from the reaction?
9 H₂O(l) + 6 Mn²⁺(aq) + 5 XeO₃(aq) → 6 MnO₄^-(aq) + 5 Xe(g) + 18 H⁺(aq)
