A student set up a Cu-Fe cell according to the procedure in Part 2. They measured the cell voltage twice at 298 K and determined the average of their measurements to be 0.682 V. Determine what the concentration of the Fe2+(aq) solution was as it should have changed due to auto-oxidation. Report your answer, in mol/L, to the appropriate number of significant figures and only report the numerical value (no units). Use the special "e" notation to answer this question. If your answer is one significant figure, do not include a decimal place (ie. 7e2 not 7.e2).

A student set up a Cu-Fe cell according to the procedure in Part 2. They measured the cell voltage twice at 298 K and determined the average of their measurements to be 0.682 V. Determine what the concentration of the Fe2+ (aq) solution was as it should have changed due to auto-oxidation. Report your answer, in mol/L, to the appropriate number of significant figures and only report the numerical value (no units). Use the special "e" notation to answer this question. If your answer is one significant figure, do not include a decimal place (ie. 7e2 not 7.e2).
