Based on the Balanced Chemical Equation Shown Below,determine the Molarity

Multiple Choice

Based on the balanced chemical equation shown below,determine the molarity of a solution containing Fe²⁺(aq) if 40.00 mL of the Fe²⁺(aq) solution is required to completely react with 30.00 mL of a 0.250 mol L^-1 potassium bromate,KBrO₃(aq) ,solution.The chemical equation for the reaction is
6 Fe²⁺(aq) + BrO₃^-(aq) + 6 H⁺(aq) → 6 Fe³⁺(aq) + Br^-(aq) + 3 H₂O(l)

A) 0.0312 mol L^-1
B) 0.188 mol L^-1
C) 1.12 mol L^-1
D) 2.00 mol L^-1
