The total number of electrons flowing through the device is approximately 3.11 x 10^20 electrons, calculated using the formulas for charge and number of electrons. By multiplying the current and time, we find the total charge, and then divide by the charge of a single electron. This method shows how to convert electrical current into the actual number of electrons that flow through a circuit.
