Calculadora da Lei de Faraday — Formula
## Faraday's Law of Electrolysis
### Formula
**m = (I × t × M) / (z × F)**
Where:
- **m** = mass deposited (g)
- **I** = current (A)
- **t** = time (s)
- **M** = molar mass (g/mol)
- **z** = charge number (electrons per ion)
- **F** = 96485 C/mol (Faraday's constant)
The mass deposited is proportional to the charge passed and the molar mass, and inversely proportional to the charge number.

Exemplo Resolvido
Electroplating copper (M = 63.55, z = 2) with 5 A for 1 hour (3600 s).
- m = (I × t × M) / (z × F)
- m = (5 × 3600 × 63.55) / (2 × 96485)
- m = 1,143,900 / 192,970
- m = 5.928 g
