Answer:
2.25*10^(20)\text{ electrons}Step-by-step explanation:

Current, I = 3.0 A

Time, t = 12 s

The quantity of charge flowing through the battery is:

Q = It

Q = 3 x 12

Q = 36 coulombs


\begin{gathered} \text{Number of electrons in 1 coulomb of charge = 6}.24\text{ }*10^(18)\text{ electrons} \\ \text{Number of electrons in 36 coulombs of charge = 6}.24\text{ }*10^(18)*36\text{ electrons} \\ \text{Number of electrons in 36 coulombs of charge = 2.25 }*10^(20)\text{electrons} \end{gathered}
