Chromium metal can be plated out from an acidic solution containing CrO3 according to the following equation.
CrO3(aq) + 6H+(aq) + 6e– → Cr(*) + 3H2O.
(i) How many grams of chromium will be plated out by 24000 coulombs?
(ii) How long will it take to plate out 1.5 g of chromium by using 12.5 ampere current?
