How many years will be required for the zinc bar

Reference no: EM13693626

Problem- A zinc bar weighing 3.0 kg is attached to a buried iron pipe to protect the pipe from corrosion. An average current of 0.020 A fows between the bar and the pipe. How many years will be required for the zinc bar to be entirely consumed? (1 year = 3.16 x 10^7 s)

Anyone can tell me how to solve it step by step so that I will be able to understand what is going on?
