Electrolysis mass calculator

Mass deposited or dissolved: m = (Q·M)/(n·F) with Q in coulombs.

Calculator

Model / formula

m = (Q · M) / (n · F) (Q in C, M in g/mol, n = mol e⁻ per mol ion, F = 96 485 C/mol)

Charge Q (C)

Molar mass M (g/mol)

n (electrons per ion in the half-reaction)

$$m = \frac{Q M}{n F}$$
