Calculate the current required to transfer 0.015 mols of electrons in a time of 20 min

  • chemistry -

    amperes x seconds = coulombs.
    95,486 coulombs = 1 mol electrons.

    What am I doing wrong?

    If a current of 54 A flows into a cell for 45 minutes 30 s, determine the mass of chronium deposited.

    My answer:
    54 x 2730 s = 147420

    147430/96485

    = 1.52 mols

    m = n x M

    =1.52 x 52
    = 79.5
