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 when 2 moles of an ideal gas expand isothermally and reversibly from an initial volume of 2 dm³ to a final volume of 20 dm³ at a temperature of 300 K, we can use the formula for the change in entropy (ΔS) for an ideal gas during an isothermal process:

\[ \Delta S = nR \ln\left(\frac{V_2}{V_1}\right) \]

Where:
- \( n \) = number of moles of gas
