Electroplating Mass Deposited (Faraday's Law) Calculator

m = (I · t · M) / (n · F).

Compute the mass of metal deposited at the cathode during electroplating from the current, time, molar mass of the metal, and number of electrons per ion using Faraday's first law of electrolysis: m = (I · t · M) / (n · F), with F = 96 485 C/mol. Defaults shown plate copper (Cu²⁺ + 2e⁻ → Cu) at 2 A for 1 hour.
