What equation should I use to solve these questions?

Question

1. A 0.23 M solution of AgNO3 is electrolyzed for 10.0 minutes with a current of 5.2 amps. What is the maximum number of grams of silver which could be plated out during the process?

2. If lead metal is produced by the electrolysis of lead (IV) oxide, how many grams of lead will be deposited by 4.1 amps during 15 minutes?

3. If lead metal is produced by the electrolysis of lead (IV) oxide, how long will it take to produce 2.6 grams of lead with current of 0.52 amps?

I know that 1 amp is 1C/sec, but how can I go from C to the answer? Your help is much appreciated.

Answer 1

96,500 coulombs is a mole of electrons. That's the relationship that you need.
