What is the corrosion current density in mA/cm² for a copper-zinc galvanic couple at 25°C with a corrosion potential of -0.462 V vs SHE for the copper electrode and a copper surface area of 10 cm², assuming that the copper electrode serves as the anode? The half-cell reactions are:

Cu --> Cu²⁺ + 2e⁻    (E° = +0.34 V vs SHE)

Zn²⁺ + 2e⁻ --> Zn    (E° = -0.76 V vs SHE)
