A chemistry student is given the following information: A galvanic cell is set up consisting of a copper electrode in a copper (II) ion solution connected by a salt bridge to a silver electrode in a silver ion solution. The concentration of the copper (II) solution is 0.10 M and the concentration of the silver ion solution is 0.025 M. The measured potential of the cell is 0.66 V. Calculate the resistance of this electrochemical cell.
