Calculadora de Masa Depositada — Fórmula

Mass from Charge in Electrolysis

Formula

m = (Q × M) / (z × F)

Where:

  • m = mass deposited (g)
  • Q = total charge passed (C) = I × t
  • M = molar mass (g/mol)
  • z = charge number
  • F = 96485 C/mol

    • This is Faraday's Law expressed in terms of total charge rather than current and time.

    Ejemplo Resuelto

    Pass 18,000 C through a silver nitrate solution (M = 107.87, z = 1).

    1. m = (Q × M) / (z × F)
    2. m = (18000 × 107.87) / (1 × 96485)
    3. m = 1,941,660 / 96485
    4. m = 20.124 g of silver
