How many minutes are needed to plate out 29.00g Mg from molten MgCl2, using 2.70A of current?
Answered by DrBob222
It takes 96,485 coulombs to plate out 1 equivalent weight of Mg which is 24.3/2 = 12.15g Mg. You want 29 g so it will take
96,485 x 29/12.15 = ? coulombs
amperes x seconds = coulombs.
You know amperes and coulombs, solve for seconds and convert to minutes.
