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.

• chemistry -

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.

54 x 2730 s = 147420

147430/96485

= 1.52 mols

m = n x M

=1.52 x 52
= 79.5
