The molar volume of He at `10 .1325MPa` and `273K` is 0.011075 of its molar volume at 101.325 kPa at `273 K` Calculate the radius of helium atom The gas is assumed to show real nature Neglect the value of a for He .

Explanation

To calculate the radius of a helium atom given the conditions in the problem, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Given Data**:
- Molar volume of He at \( P_1 = 10.1325 \, \text{MPa} \) and \( T = 273 \, \text{K} \) is \( V_1 \).
- Molar volume of He at \( P_2 = 101.325 \, \text{kPa} \) and \( T = 273 \, \text{K} \) is \( V_2 \).
- The relationship given is \( V_1 = 0.011075 \times V_2 \).
