The charge of one electron is -1.602 x 10^-19 C. To find the number of electrons needed to make 80µC, we can divide the total charge by the charge of one electron.

No. of electrons = (80 x 10^-6 C) / (-1.602 x 10^-19 C)

= 4.996 x 10^13 electrons

Therefore, it takes approximately 5.0 x 10^13 electrons to make 80µC of charge.
