The total charge that flows through an electric device delivering a current of 15.0 A for 30 seconds is 450 Coulombs, which corresponds to approximately 2.81 x 10^21 electrons. This is calculated using the relations between current, charge, and time, and the charge of a single electron. Therefore, about 2.81 x 10^21 electrons flow through the device.
