How many electrons are there in one coulomb of electricity?

Options

A. `6.023xx10^(23)`
B. `1.64xx10^(-24)`
C. `6.24xx10^(18)`
D. `6.24xx10^(-24)`

Answer

To find out how many electrons are there in one coulomb of electricity, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the charge of one electron**:
The charge of one electron is approximately \( 1.602 \times 10^{-19} \) coulombs.

2. **Set up the equation**:
We know that the total charge (Q) is 1 coulomb. To find the number of electrons (n), we can use the formula:
\[ n = \frac{Q}{e} \]
where \( e \) is the charge of one electron.

3. **Substitute the values**:
Substitute \( Q = 1 \) coulomb and \( e = 1.602 \times 10^{-19} \) coulombs into the equation:
\[ n = \frac{1 \text{ C}}{1.602 \times 10^{-19} \text{ C/electron}} \]

4. **Calculate the number of electrons**:
Performing the division:
\[ n = \frac{1}{1.602 \times 10^{-19}} \approx 6.24 \times 10^{18} \]

5. **Conclusion**:
Therefore, there are approximately \( 6.24 \times 10^{18} \) electrons in one coulomb of electricity.

### Final Answer:
There are approximately \( 6.24 \times 10^{18} \) electrons in one coulomb of electricity.
