You have a 5.00 cm diameter sphere that you would like to have plated with copper metal. How long will it take to electroplate a 40.0 micron thick coating onto the sphere using Cu+2 and a current of 3.00 amps? The density of copper is 8.94 g/cm³. 1 micron = 1.00×10-4 cm. [hint: Calculate the difference in volume of the coated and uncoated spheres and then use the density information to determine your answer.] R
