A student wants to electroplate a nickel wire with copper. The student has 1 g of copper sulfate and a 2 M solution of sulfuric acid. The wire has a surface area of 3 cm², and the desired copper thickness on the wire is 0.025 cm. How long should the student electroplate the wire with a current of 1.5 A to achieve the desired thickness of copper? Calculate the current density in the electrochemical cell.
