The ratio of excluded volume (`b`) to molar volume of a gas molecule is

Options

A. `1`
B. `2`
C. `3`
D. `4`

Explanation

To find the ratio of excluded volume (b) to the molar volume of a gas molecule, we can follow these steps:

### Step 1: Understand the concept of excluded volume
Excluded volume (b) is the volume that is not available for movement due to the presence of gas molecules. It is often considered as the volume occupied by the gas molecules themselves.

### Step 2: Determine the expression for excluded volume
For spherical molecules, the excluded volume (B) is defined as:
\[ B = 4 \times \text{(actual volume of one molecule)} \]
