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.
