A student is given a galvanic cell that has a copper electrode and a silver electrode. The concentration of copper ions in the solution surrounding the copper electrode is 1.0 M, and the silver electrode is submerged in a solution of AgNO3 with a concentration of 0.1 M. The cell temperature is 25°C. Calculate the resistance of the electrochemical cell given that the cell is at equilibrium and the cell potential is measured to be 0.46 volts.
