-9.649xx10^4C, rounded to three decimal places

Explanation:

One mole is equal to 6.02214179×10^23 elementary units such as atoms or molecules etc. This number is called Avogadro's number.
This implies that
1 mol of electrons means 6.0221xx10^23 electrons.
We know that charge on 1 electron is -1.6022 xx 10^-19 C
:. cahrge on 1 mol of electrons=6.0221×10^23xx(-1.6022 xx 10^-19)
=-9.649xx10^4C, rounded to three decimal places
