Question

Calculate the number of electrons present in 2 coulomb of charge

Answer 1

One electron possesses a charge of :
$e=1.602 \times 10^{-19} \, \, C$

We are given a total of 2 C charge. Let us assume there are n electrons making up that 2 C charge. 


We have:

$ne = 2 \\ \\ \\ \implies n \times 1.602 \times 10^{-19} = 2 \\ \\ \\ \implies n = \frac{2}{1.602 \times 10^{-19}} \\ \\ \\ \implies \boxed{n \approx 1.248 \times 10^{19}}$


Thus, there are approximately $1.248 \times 10^{19}$ electrons in 2 coulomb charge.
