An inexpensive and accurate method of measuring the quantity of electricity passing through a circuit is to pass it through a solution of a metal ion and weigh the metal deposited. A silver electrode immersed in an Ag solution weighs 1.7854 g before the current passes and weighs 1.9274 g after the current has passed. how many coulombus have passed?
