Answer #1

q = ne

17.75* 10^-6 = n * 1.6* 10^-19

n = 1.108* 10^14 electrons

======

Comment before rate in case any doubt, will reply for sure.. goodluck

    To relate current, time, charge, and mass for electroplating calculations. 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. Electric current is measured in amperes (A ), which expresses the amount of charge, in coulombs (C ), that flows per second (s ): 1 A=1 C/s Another unit of charge is the faraday (F ), which is equal to a mole of electrons and...
