(ii) As part of a corrosion test, nickel (II) immersed in boiling 10% phosphoric acid exhibited a corrosion rate of 154 mils/year. Given nickel's mass density of 8.90g/cm and atomic weight of 58.7 g/mol, determine: (1) The mass loss per unit surface area (cm2) of nickel after 1 hr, and (2) The corrosion current density, in mA/cm2.
