# Using Faraday's Law to solve an electrochemical thermodynamics problem, considering an iron sample protected by nickelization

An iron sample (surface area of 3.3 cm^2) was protected by nickelization in a solution containing 0.1 M NiSO4 and 1 M H2SO4 at a current of 0.28 A for 30 min.

What will be the sample weight increase after the process of nickelization upon 62% current efficiency?

Please show step by step solution.
