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 M 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 M
B) 0) 188 M
C) 1) 12 M
D) 2) 00 M
