Calculate the total resistance of an electrochemical cell consisting of two half-cells where one half-cell has a copper electrode submerged in a 0.5 M CuSO4 solution, and the other half-cell has a zinc electrode submerged in a 1.0 M ZnSO4 solution. The copper electrode is connected to the zinc electrode through a salt bridge. The resistance of the salt bridge is 22 ohms, and the resistance of the copper and zinc electrodes are negligible.
