The van der Waals constant `b` of `Ar` is `3.22xx10^(-5) m^(3) mol^(-1)`. Calculate the molecular diameter of `Ar`.

Explanation

To calculate the molecular diameter of Argon (Ar) using the van der Waals constant \( b \), we can follow these steps:

### Step 1: Understand the relationship between \( b \) and molecular volume
The van der Waals constant \( b \) is related to the volume occupied by one mole of gas molecules. The formula is given by:
\[ b = 4 \times V_m \]
where \( V_m \) is the volume occupied by a single molecule in one mole of gas.
