3. Calculate the mass of iron (III) in 100.0 ml of the analyzed solution, if the complete reduction of it to iron (II) in 10.00 ml of this solution at a constant potential required the same amount of electricity as is necessary to isolate 0.1658 g of copper in a copper coulometer. Write the equations of electrochemical reactions occurring in coulometric cells.
