Question

wt is the charge carried by 12.5×10 to the power 8 electrons​

Answer 1

Answer:

Charge on one proton = 1.6 * 10^-19 C

So Total charge carried = 12.5 * 10^8 * 1.6 * 10^-19 C

= 2 * 10^ -10 C

Answer 2

Answer:

2*10^-10

Explanation:

1.6 *10^-19 is the charge of an electron

so charge of 12.5*10^8 electrons is

12.5*1.6*10^-11

20*10^-11
