When a sample of the aqueous layer with a volume of 13.61 mL is collected, it requires 18.71 mL of a titrant solution of S2O32- with a concentration of 0.01867 M to reach the endpoint. The reaction has a 2:1 mole ratio of thiosulfate to all reducible iodine species. Calculate the concentration of total reducible iodine (mole/L) in the aqueous layer.
