Based on the balanced chemical equation shown below, determine the concentration (M) of Fe²⁺ (aq) if 40.00 mL of the Fe²⁺ (aq) solution is required to completely react with 41.48 mL of a 0.125 M bromate, BrO₃ - (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)
