A student determined the concentration of total reducible iodine in the aqueous phase based on the average of their 'best two' determinations in Part 1 to be 0.0177 M. They also determined the concentration of I2 in the CH2Cl2 phase based on the average of their 'best two' determinations in Part 2 to be 0.0200 M. Determine what the concentration of I- in water would be based on this student's previous work. Report your final answer, in mol/L, to 3 decimal places and only include the numerical value (no units). Do not use scientific notation for this question.
