The amont of of I3- in a solution can be determined by the titration with a solution containinig a known concentration of (S2O3)2- (thiosulfate ion). The determination is based on the net ionic equation 2S2(O3)2-(aq) + I3-(aq) > S4(O6)2-(aq) + 3I-(aq). Given that it requires 42.8mL of a 0.320M Na2S2O3(aq) to titrate a 10.0 mL sample of I3- (aq), caluculate the molarity of I3-(aq) in the solution
