Determine the concentration of the unknown copper solution if the measured cell potential is 1.05 volts? Consider the following galvanic cell, consisting of a zinc rod immersed in a 0.015 M ZnCl2 solution and a copper rod immersed in a solution of CuSO4 of unknown concentration.
Zn2+ + 2e- =Zn E = -0.763 V
Cu2+ + 2e- =Cu E=+0.337 V
