Answer:

The net electric charge is
-1.352*10^(-12)\ C

Step-by-step explanation:

Given that,

No of electron
n=8.45*10^(6)

We need to calculate the net electric charge in coulombs

Using formula of net electric charge

Net electric charge = number of electron X charge of one electron


Q=ne

Put the value into the formula


Q=8.45*10^(6)*(-1.6*10^(-19))


Q=-1.352*10^(-12)\ C

Hence, The net electric charge is
-1.352*10^(-12)\ C
