Helium weighing `16 g` is expanded from `1atm` to one-tenth of its original pressure at `30^(@)C`. Calculate the change in entropy assuming it to be an ideal gas.

Explanation

To calculate the change in entropy (ΔS) for the expansion of helium gas, we can follow these steps:

### Step 1: Determine the number of moles of helium
Given:
- Mass of helium (m) = 16 g
- Molar mass of helium (M) = 4 g/mol

Using the formula for the number of moles (n):
...
