For oxygen gas, has van der Waals constant b is `"0.318 L mol"^(-1).` Calculate the diameter of oxygen molecule.

Explanation

To calculate the diameter of an oxygen molecule using the van der Waals constant \( b \), we can follow these steps:

### Step 1: Understand the relationship between \( b \) and the volume of the molecule
The van der Waals constant \( b \) is related to the volume occupied by one mole of gas molecules. It can be expressed as:
\[ b = 4 \times V_{\text{molecule}} \times N_A \]
where \( V_{\text{molecule}} \) is the volume of a single molecule and \( N_A \) is Avogadro's number (\( 6.022 \times 10^{23} \, \text{mol}^{-1} \)).
