Faraday Electrolysis: Charge to Moles Deposited Calculator

Moles and mass deposited at an electrode from electric charge.

Uses Faraday's laws of electrolysis to calculate moles deposited: n = Q / (z · F), where Q is charge in coulombs, z is ion valence, and F = 96485 C/mol. Also computes the mass deposited.
