The correct Answer is:
To find the number of electrons in a charge of 1.6 C, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Charge of an Electron**: The charge of a single electron is approximately \( e = 1.6 \times 10^{-19} \) coulombs. 2. **Use the Formula for Total Charge**: The total charge \( Q \) can be expressed in terms of the number of electrons \( n \) and the charge of one electron: \[ Q = n \cdot e \] 3. **Rearrange the Formula to Solve for \( n \)**: We can rearrange the equation to find \( n \): \[ n = \frac{Q}{e} \] 4. **Substitute the Values**: Substitute \( Q = 1.6 \, \text{C} \) and \( e = 1.6 \times 10^{-19} \, \text{C} \): \[ n = \frac{1.6 \, \text{C}}{1.6 \times 10^{-19} \, \text{C}} \] 5. **Calculate \( n \)**: Simplifying the expression: \[ n = \frac{1.6}{1.6 \times 10^{-19}} = \frac{1.6}{1.6} \times 10^{19} = 1 \times 10^{19} \] Thus, \[ n = 10^{19} \] ### Final Answer: The number of electrons in a charge of 1.6 C is \( 10^{19} \). ---
