What is the molarity of a potassium triiodide solution, KI3(aq), if 30.00 mL of the solution is required to completely react with 25.00 mL of a 0.500 M thiosulfate solution, K2S2O3(aq)? The chemical equation for the reaction is:

2 S2O32-(aq) + I3-(aq) → S4O62-(aq) + 3 I-(aq).

A) 0.208 M
B) 0.300 M
C) 0.417 M
