Calculate the number of atoms in :
(i) 0.25 moles atoms of carbon
(ii) 0.20 mole molecules of oxygen.

Explanation

To solve the question, we will break it down into two parts:

### Part (i): Calculate the number of atoms in 0.25 moles of carbon.

1. **Understand the relationship between moles and atoms**:
- 1 mole of any substance contains Avogadro's number of entities, which is approximately \(6.022 \times 10^{23}\).

2. **Use the formula to calculate the number of atoms**:
