If the electroplating apparatus operates at 1.40 , how long will it take the zinc to

  1. Nov 28, 2011 #1
    Wow. Can anyone please tell me how to approach this problem?

    For a science experiment you need to electroplate zinc onto both sides of a very thin, 1.00 1.00 copper sheet. You want the zinc thickness to be 140 , and you know that the charge carriers in the ionic solution are divalent (charge ) zinc ions. The density of zinc is 7140 .

    If the electroplating apparatus operates at 1.40 , how long will it take the zinc to reach the desired thickness?

    Why don't you show us how far you got? You know, that thing in the template which somehow is missing from your message.

    that's the thing. Mastering Physics hw assignments give problems that are not covered in lecture or in the book. That is why I don't even know how to approach this problem, or what formula to use :T
