A certain particle carries `2.5 xx 10^(-16) C` of static electric charge. Calculate the number of electrons present in it.

Explanation

To solve the problem of calculating the number of electrons present in a particle that carries a charge of \(2.5 \times 10^{-16} \, \text{C}\), we can follow these steps:

### Step 1: Understand the Charge of an Electron
The charge of a single electron is approximately \(e = 1.602 \times 10^{-19} \, \text{C}\).

### Step 2: Use the Formula Relating Charge and Number of Electrons
The total charge \(Q\) of the particle can be expressed in terms of the number of electrons \(n\) and the charge of a single electron \(e\):
\[
