A Solid contains `5 xx 10^(21)` number of atoms. If an electron is removed from each of 0.01% of number of atoms, find the charge gained by this solid?

Explanation

To solve the problem step by step, we will follow these calculations:

### Step 1: Calculate the number of atoms from which electrons are removed.
Given that the total number of atoms in the solid is \( 5 \times 10^{21} \) and electrons are removed from \( 0.01\% \) of these atoms.

\[ \text{Number of atoms from which electrons are removed} = 0.01\% \text{ of } 5 \times 10^{21} \]
