A concentration cell is built based on the following half reaction by using two pieces of zinc as electrodes (each weighing 100.0 g), two Zn2+ solutions, 0.105 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 0.009916 V at 307 K?
Zn2+ + 2 e- ? Zn Eo = -0.761 V
