Question

What is the total charge of 1.0g of electrons?

Answer 1

1.0 gram (g) of electrons would contain 10^27 electrons
Electrons have an electric charge of −1.602×10−19 coulomb
so total charge of 1 g electrons = -1.602 x 10^-19 x 10^27 = -1.602 x 10^8

Answer 2

mass of 1e=9.10938291(40)×10^-31kg
=9.109*10^-28g
charge mass
−1.602176565(35)*10^-19 9.109*10^-31kg
X 9.109*10^-28g

=> X=9.109*10^-31 * 9.109*10^-28g
-------------------------------
−1.602*10^-19
=>5.179393320849e-77

i have done my best
sorry if wrong

Answer 3

One electron mass is 9.109*10^(-28) g, so there are 1/(9.11*10^(-28)) = 1.098*10^27 electrons per gram. One electron charge is 1.602*10^(-19) C, so the charge of a gram of electrons is (1.098*10^27)(1.602*10^(-19)) C = 1.759*10^8 C.
