The number of electrons flowing through an electric device with a current of 15.0 A for 30 seconds is approximately 2.8 × 10^{21} electrons. This is calculated using the total charge formula and the charge of a single electron. The process involves calculating total charge and then converting that charge into the number of electrons based on their individual charge.
