A concentration cell is built based on the following half reaction by using two pieces of iron as electrodes (each weighing 100.0 g), two Fe3+ solutions, 0.149 M and 0.431 M (both exactly 1.00 L in volume), and all other materials needed for a galvanic cell. What will the mass of the anode electrode be when the cell potential is 0.004951 V at 289 K?
Fe3+ + 3 e- ? Fe Eo = -0.036 V
