Options

A. `1.6 xx 10^(-19)C`
B. 96500C
C. `6.02 xx 10^(-23)C`
D. `1.6 xx 10^(-23)C`

Answer

To find the amount of electric charge on one mole of electrons, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept**: The electric charge (Q) on one mole of electrons can be calculated using the formula:
\[ Q = n \times e \]
where \( n \) is the number of electrons in one mole (Avogadro's number) and \( e \) is the charge of one electron.

2. **Identify the Values**:
- The charge of one electron (\( e \)) is approximately:
\[ e = 1.602 \times 10^{-19} \text{ C} \]
- Avogadro's number (\( n \)) is:
\[ n = 6.022 \times 10^{23} \text{ electrons/mole} \]

3. **Substitute the Values into the Formula**:
\[ Q = (6.022 \times 10^{23}) \times (1.602 \times 10^{-19}) \]

4. **Calculate the Charge**:
- First, multiply the numbers:
\[ Q = 6.022 \times 1.602 \times 10^{23} \times 10^{-19} \]
- This simplifies to:
\[ Q = 9.647 \times 10^{4} \text{ C} \]

5. **Round the Result**:
- The value \( 9.647 \times 10^{4} \) C can be approximated to:
\[ Q \approx 96500 \text{ C} \]

6. **Final Answer**:
- Therefore, the amount of electric charge on one mole of electrons is:
\[ \text{Answer: } 96500 \text{ C (which is also equal to 1 Faraday)} \]
