If `v` is the volume of one molecule of a gas under given conditions, then van der Waals constant `b` is

Options

A. `4v`
B. `4v//N_(0)`
C. `N_(0)//4v`
D. `4vN_(0)`

Explanation

To solve the question regarding the van der Waals constant \( b \) in relation to the volume of one molecule of a gas, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the van der Waals Equation**:
The van der Waals equation for real gases is given by:
\[
\left( P + \frac{a n^2}{V^2} \right)(V - nb) = nRT
