Consider a zinc-copper electrochemical cell in which the half-reaction Zn(s) → Zn²⁺(aq) + 2e⁻ occurs at the anode and the half-reaction Cu²⁺(aq) + 2e⁻ → Cu(s) occurs at the cathode. If the concentration of Zn²⁺(aq) in the anode compartment is 0.500 M and the concentration of Cu²⁺(aq) in the cathode compartment is 0.0250 M, calculate the current density when a current of 2.50 A is passed through the cell. (Assume that the temperature and pressure are constant and that the electrodes are inert.)
