How many electrons are there in 3.2 coulomb?

Answer 1

3.2 millicoulomb (1 coulomb/1000 millicoulomb)

= 0.0032 coulomb

--------------------------

Charge on one electron sans negative sign...,

1.602 X 10 -19 coulomb

---------------------------so,

0.0032 coulomb/1.602 X 10 -19 coulomb

= 2.0 X 1016 electrons

================

Answer 2

3.2 coulomb = 1.88 x 1019 electrons, give or take two or three

Answer 3

1 electron has a charge of -1.6019 x 10-19 Coulombs. so 3.2 x 10 = 32 Copper atoms must have a positive charge. So 32 x 1.6019 x 10-19 = 5.12608 x 10-18 Coulombs.

Answer 4

There are approximately 2 x 10^19 electrons in 3.2 coulombs of charge, based on the charge of one electron being approximately -1.6 x 10^-19 coulombs.
