There are about _____electrons in a charge of -1 coulomb.

Explanation

To find the number of electrons in a charge of -1 coulomb, we can use the formula that relates charge (Q), the number of electrons (N), and the charge of a single electron (e):

1. **Identify the known values**:
- Total charge (Q) = -1 coulomb
- Charge of one electron (e) = -1.6 × 10^(-19) coulombs

2. **Use the formula**:
The relationship between charge, number of electrons, and the charge of one electron is given by:
...
