Question

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 0.125 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) 0.0156 M
B) 0.0938 M
C) 0.562 M
D) 1.00 M
