Michael performed an experiment to analyse iron content by coulometry. A sample with mass of 0.8202 g was analysed against platinum cathode. During the reaction, 103.2775 C were required to reduce Fe(III) to Fe(II). Deduce the percentage of Fe2(SO4)3 (399.88 g/mol) in this sample. (F = 96485 C/mol e)

A galvanic cell is based on the following half-reactions: In this cell, the copper compartment contains a copper electrode and [Cu2+] = 1.00 M, and the vanadium compartment contains a vanadium electrode and V2+ at an unknown concentration. The compartment containing the vanadium (1.00 L of solution) was titrated with 0.0800 M H2EDTA2, resulting in the reaction H2EDTA2(aq)+V2+(aq)VEDTA2(aq)+2H+(aq)K=? The potential of the cell was monitored to determine the stoichiometric point for the process, which occurred at a volume of 500.0 mL H2EDTA2 solution added.
