A metal rod made of iron is coupled with a zinc rod in an aqueous medium. If the corrosion potential of the iron rod is -0.44 V and that of the zinc rod is -0.76 V, calculate the corrosion current density of the iron rod when coupled with the zinc rod at 25°C. The polarization resistance of the iron rod is 880 Ωcm².
