The charge of an electron is equal to: 1.6E-19 C

C - Coulombs - SI unit of electric charge

Coulomb was introduced as the unit of charge before the discovery of the electron. Coulomb turned out to be a very large unit. Calculate the number of extra electrons needed to accumulate a charge of 1 Coulomb.

1/1.6E-19, or about 6E18.

i don't get what it means by 'extra' electrons, but if you're working out the number for 1 Coulomb, then it's going to be
1/(1.6E-19)
which will turn out to be a very big number indeed.

If by 'extra' it means you already start with one electron, and how many are needed to complete up to 1C, then it owuld be
(1/(1.6E-19))-1

Hope this helps.
