Question

What is the estimate size of an electron in Coulomb per gram?​

Answer 1

1 electron has a mass of 9.11 x 10^-28 g. So there are 1.1 x 10^27 electrons in 1 gram. You know as well the charge of 1 electron which is 1,6 10^-19 C. So you should be able to calculate the total charge in Coulomb of 1 gram of electrons being 1.76 10^8 C
