Electrochemistry can be used to measure electric current in a silver coulometer. The cathode is weighed before and after the passage of the current. A silver cathode initially has a mass of 10.77 grams and its mass increases to 12.89 grams after current has flowed for 15.0 minutes. Compute the quantity of charge in coulombs and the current in amperes.

#### Solution Preview

To answer this question, one must use Faraday's constant which is 96,490 C/mole of electrons.

Since we know that silver(Ag) is probably in the plus one state Ag+, it requires one electron to become Ag ...
