Given Information:
Charge = q = 7.0x10⁻⁶ C
Required Information:
Number of electrons = n = ?
Answer:
Number of electrons = 4.375x10¹³
Explanation:
We know that charge is given by
q = n*e
Where n is the number of electrons and e is the electronic charge that is 1.60x10⁻¹⁹ C
n = q/e
n = 7.0x10⁻⁶/1.60x10⁻¹⁹
n = 4.375x10¹³ electrons
Therefore, 4.375x10¹³ electrons were transferred.
