A student performed three aqueous layer titrations in Part 1 using a standard sodium thiosulfate solution with a concentration of 0.01155 M. They reported the following measurements: Final Aqueous Layer Burette Reading Initial Aqueous Layer Burette Reading Final Thiosulfate Burette Reading Initial Thiosulfate Burette Reading Determination #1 16.33 mL 6.50 mL 31.98 mL 0.76 mL Determination #2 26.76 mL 16.33 mL 33.62 mL 0.88 mL Determination #3 36.95 mL 26.76 mL 32.22 mL 0.41 mL What is the concentration of reducible iodine (in mol/L) in the aqueous phase based on the data from their third titration (ie. their third determination)? Report your answer to the correct number of significant figures and only report the numerical value (no units).
