Chromium metal can be plated onto an object from an acidic solution of dichrmonate tions. What average current is required to plate 17.8 g of chronium metal in a time of 2.20 h? ( you will need to construct your own equation for the halfreaction)

bobpursley,
Write the equation, determine the the atoms of chronoum metal, and then from the balaced equation the number of electrons to balance the equations.
amps= 1/chargeonelectron * total charge /time
