Question #23427

How many electrons must pass through the circuit for 767 coulombs of charge

Expert's answer

The magnitude of the electrical charge of one mole of elementary charges(approximately 6.022 × 10^{23} , or Avogadro's number ) is known as a Faraday unit of charge (closely related to the Faraday constant ).

One Faraday is equal to 96485.3399 coulombs. In terms of Avogadro's number N_{A}, one coulomb is equal to approximately 1.036 × N_{A} × 10^{−5} elementary charges.

760 coulomb * 1.036 × N_{A} × 10^{−5} = 7.8736 × N_{A} × 10^{−3}

One Faraday is equal to 96485.3399 coulombs. In terms of Avogadro's number N

760 coulomb * 1.036 × N
