Calculate number of atoms in each of the following"
i. 0.5 mol atom of nitorgen
ii. 0.2 mol molecules of hydrogen

Explanation

To solve the question of calculating the number of atoms in each of the following scenarios, we will use Avogadro's number, which is \(6.022 \times 10^{23}\). This number represents the number of particles (atoms, molecules, etc.) in one mole of a substance.

### Step-by-Step Solution:

**i. Calculate the number of atoms in 0.5 mol of nitrogen:**

1. **Identify the number of moles**: We have 0.5 moles of nitrogen.
