How much copper would be plated by a current of 1.5 A in a time of 1.0 h?

Answer 1

an ampere is a Coulomb per second

there are 6.242E18 electrons in a Coulomb

moles of electrons = (6.242E18 * 1.5 * 60 * 60) / 6.02E23

it takes two electrons to plate a Cu atom

find the moles of electrons
... divide by two to find the moles of Cu

multiply by the molar mass of Cu to find the grams
