plshelp part C

For a large batch of nails, a manufacturer needs to plate a total zinc mass of 2.80 kg on the surface to get adequate coverage. Learning Goal: To relate current, time, charge, and mass for electroplating calculations. Part A Electroplating is a form of electrolysis in which a metal is deposited on the surface of another metal. To quantify electrolysis, use the following relationships. How many moles of zinc are in 2.80 kg of zinc? Electric current is measured in amperes (A), which expresses the amount of charge, in coulombs (C), that flows per second (s): Express your answer to three significant figures and include the appropriate units. 1 A = 1 C/s 42.8 mol Another unit of charge is the faraday (F), which is equal to a mole of electrons and is related to charge in coulombs as follows: Submit Previous Answers 1F = 1 mol e¯ = 96, 500 C v Correct Part B How many coulombs of charge are needed to produce 42.8 mol of solid zinc? Express your answer to three significant figures and include the appropriate units. 8.26x106 C Submit Previous Answers Correct Part C With a power supply able to produce 125 A of current, how long must the nails stay in the electrolysis chamber to receive 8.26x106 C of charge?
