Calculate the entropy change when `2 mol` of an idela gas expand isothermally and reversibly from an initial volume of `2 dm^(3)` to `20 dm^(3)` at `300 K`.

Explanation

To calculate the entropy change (ΔS) when 2 moles of an ideal gas expand isothermally and reversibly from an initial volume (V1) of 2 dm³ to a final volume (V2) of 20 dm³ at a temperature (T) of 300 K, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Data:**
- Number of moles (N) = 2 mol
- Initial volume (V1) = 2 dm³
- Final volume (V2) = 20 dm³
