Homework Help: chemistry

Posted by Amandeep on Tuesday, April 22, 2008 at 11:25pm.

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
