The electric charge on one electron is `1.602 xx 10^(-19)` coulomb. How much charge is present on 0.1 mole of `Cu^(2+)` ions ?

Explanation

To find the total electric charge present on 0.1 mole of \( \text{Cu}^{2+} \) ions, we will follow these steps:

### Step 1: Understand the charge of \( \text{Cu}^{2+} \) ions
Each \( \text{Cu}^{2+} \) ion has a charge of \( +2 \) elementary charges. This means that each ion carries a charge equivalent to two electrons.

### Step 2: Calculate the charge of one mole of \( \text{Cu}^{2+} \) ions
Since one mole of any substance contains Avogadro's number of entities (ions, in this case), we can calculate the total charge for one mole of \( \text{Cu}^{2+} \) ions:
- The charge of one electron is \( 1.602 \times 10^{-19} \) coulombs.
