Question

How much charge is represented by 4,600 electrons?

Answer 1

We can find the charge from the formula:

$$Q = Ne,$$

here, $N = 4600$ is the quantity of the electrons, $e = 1.6 \cdot 10^{-19} \ C$ is the charge of the electron.

Then, we get:

$$Q = 4600 \cdot 1.6 \cdot 10^{-19} \ C = 7.36 \cdot 10^{-19} \ C.$$

Answer:

$Q = 7.36 \cdot 10^{-19} \ C.$
