Find mass deposited by electrolysis (Faraday's law).

Current (A)

Time

Molar mass (g/mol)

Electrons (n)

Mass deposited 2.371

Formula: mass = (I · t · M) ÷ (n · 96,485)

Step-by-step with your numbers:

1. Values used:

2. Current = 2 A

3. Time = 3,600

4. Molar mass = 63.55 g/mol

5. Electrons (n) = 2

7. Mass deposited = 2.371

Did we solve your problem today?

Faraday's law gives the mass deposited or dissolved during electrolysis.

The math behind it

mass = (current × time × molar mass) ÷ (electrons transferred × 96,485 C/mol).

Copper (M 63.55, n 2), 2 A for 1 h → ~2.37 g.

Faraday constant?

96,485 C per mole of electrons.
