What is the value of `b` (van der Waals constant) if the diameter of a molecule is `2.0 A`

Options

A. `~~2.4mL mol^(-1)`
B. `~~4.8mL mol^(-1)`
C. `~~7.2mL mol^(-1)`
D. `~~9.6mL mol^(-1)`

Explanation

To find the value of the van der Waals constant \( b \) given the diameter of a molecule is \( 2.0 \, \text{Å} \), we can follow these steps:

### Step 1: Determine the radius of the molecule
The radius \( r \) is half of the diameter. Given the diameter is \( 2.0 \, \text{Å} \):
\[ r = \frac{2.0 \, \text{Å}}{2} = 1.0 \, \text{Å} \]
