A copper electrode is immersed in a 0.1M solution of CuSO4 and a zinc electrode is immersed in 0.1M solution of ZnSO4. Both the solutions are connected with a salt bridge. If the standard reduction potentials of Cu2+/Cu and Zn2+/Zn are +0.34V and -0.76 V respectively, calculate the potential difference between the two electrodes at 25°C.
