A car bumper is plated with chromium using chromium(III) ions in solution. If a current of 54 A flows in the cell for 45 min 30 s, determine the mass of chronium deposited on the bumper.

  • chemistry -

    amperes x seconds = coulombs
    1 coulomb will plate 1 equivalent weight of Cr.
    1 equivalent weight Cr = atomic mass/change in # electrons for the half cell for Cr.
