Calculate the resistance of an electrochemical cell with a cell potential of 1.5 V and current flow of 0.25 A when the concentration of copper(II) ions in the cathode compartment is 0.25 M and the concentration of zinc ions in the anode compartment is 0.50 M. The cell has two electrodes made of platinum and the temperature is 25°C. (Assume the transfer of electrons and ions is 100% efficient.)
