Answer:
# _electron = 4.375 10¹³ electrons
Explanation:
In this exercise it is indicated that 7.1 μC is transferred, let's use a direct ratio or rule of three. If an electron has a charge of 1.6 10⁻¹⁹ C, how many electrons have a charge of 7.0 10⁻⁶ C
# _electron = 7.0 10⁻⁶ C (1 electron / 1.6 10⁻¹⁹ C)
# _electron = 4.375 10¹³ electrons
