Final answer:
It takes approximately 2.37 x 10^19 electrons to make up 3.79 C of charge.
Step-by-step explanation:
The charge of an electron is -1.6 x 10-19 C.
To determine the number of electrons needed to make up 3.79 C of charge, we divide the total charge by the charge per electron. So, the number of electrons would be:
Number of electrons = Total charge / Charge per electron
= 3.79 C / (-1.6 x 10-19 C)
By calculating this, we find that it takes approximately 2.37 x 1019 electrons to make up 3.79 C of charge.
