Calculate the corrosion rate of a copper metal when it is placed in a galvanic couple with zinc metal. The potential difference between the two metals is measured to be 1.5 V and the surface area of the copper metal is 2 cm². The density of copper is 8.96 g/cm³ and its atomic weight is 63.546 g/mol. The atomic weight of zinc is 65.38 g/mol and its density is 7.14 g/cm³. At constant temperature and pressure, assume that the Faraday constant is 96,485 Coulombs/mol and that one mole of electrons is equivalent to one Faraday.
