Electrochemistry – Predicting Battery Life

A rechargeable battery contains an electrochemical cell where the cathode is nickel oxide and the anode is cadmium. Over time, the cell discharges as Ni(OH) converts to NiO(OH) and cadmium oxidizes to Cd(OH)2. If the battery contains 0.5 mol of cadmium, calculate how many coulombs of charge it can deliver before fully discharging. Assume the reaction is at 100% efficiency.
