Question

calculate the no of electrons containly 100 c of charge

Answer 1

In 1 Coloumb = 1.6 * 10 exp(-19) electrons
In 100 Coloumb = 1.6 * 10 exp(-17) electrons

Answer 2

The charge of one electron is  $1.602*10^{-19} C$

We are asked to calculate the total number of electrons in charge of 100 C.

                           $We\ have\ 1.602*10^{-19} C= 1\ electron$

                                                  ⇒  $1C=\frac{1}{1.602*10^{-19}}electrons$

                                                 ⇒   $100C\ =\ 100*\frac{1}{1.602*10^{-19}}\ electrons$

                                                  ⇒  $=6.242*10^{20} \ electrons$

Hence, the total number of electrons contained by 100 C of charge is  $6.242*10^{20}$
