A student is given a concentration of 0.1 M of CuSO4 and 0.2 M of AgNO3, and is asked to calculate the total resistance of an electrochemical cell with electrodes made of these two solutions separated by a salt bridge. The standard reduction potentials for Cu and Ag are +0.34 V and +0.80 V, respectively. Calculate the total resistance of the cell at 25°C assuming that the cell has a thickness of 1 cm and a cross-sectional area of 10 cm².
