(8.8)"."10^-6 "Coulombs"

Explanation:

color(blue)"Electric charge density"

q = n e

Where,
q: is the symbol used to represent charge, (C)
n: is a positive or negative integer, "(electrons)"
e: is the electronic charge, 1.60 " x " 10^-19 "C/electrons".

So, for each one:

"Charge of one electron" = -1.6x10^-19 C#

"Charge of one proton" = +1.6 x10^-19 C#

"For more than one; the total charge is:"

n = (8.2 - 2.7)"."10^13 = (5.5)"."10^13

q = (5.5" "10^13) 1.60 " x" 10^-19 "C/electrons"

= color(blue)(8.8 " x"10^-6) "Coulombs"
