A student performed three aqueous layer titrations in Part 1 using a standard sodium thiosulfate solution with a concentration of 0.01153 M. They reported the following measurements:

	Determination #1	Determination #2	Determination #3
Final Aqueous Layer Burette Reading	14.98 mL	24.98 mL	35.09 mL
Initial Aqueous Layer Burette Reading	5.19 mL	14.99 mL	24.98 mL
Final Thiosulfate Burette Reading	30.95 mL	31.89 mL	31.95 mL
Initial Thiosulfate Burette Reading	0.05 mL	0.22 mL	0.03 mL

How many moles of thiosulfate did they use in their first titration (ie. their first determination)? Report your answer to the correct number of significant figures and only report the numerical value (no units).
