Final answer:

To calculate the number of electrons required to make 80 Coulombs of charge, divide the total charge by the charge of a single electron, which is 1.602 x 10^-19 C. The result is 5.0 x 10^20 electrons. The answer to the question is 5.0 x 1020 electrons (Option c).

Step-by-step explanation:

The question is asking how many electrons it takes to make 80 Coulombs (C) of charge. To find the number of electrons needed to make a certain charge, we use the fundamental charge of an electron, which is approximately 1.602 x 10-19 C. Therefore, we divide the total charge by the charge of one electron to find the number of electrons:

Number of electrons (ne) = Total charge (Q) ÷ Charge per electron (e)

ne = 80 C ÷ 1.602 x 10-19 C/e

ne = 5.0 x 1020 electrons

So, the answer to the question is 5.0 x 1020 electrons (Option c).
