The rate of diffusion of methane is twice that of `X`. The molecular mass of `X` is divided by `32`. What is value of `x` is ?

Options

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

Explanation

To solve the problem step by step, we will use Graham's law of effusion, which states that the rate of diffusion of a gas is inversely proportional to the square root of its molar mass.

### Step-by-step Solution:

1. **Understanding the Problem**:
We know that the rate of diffusion of methane (CH₄) is twice that of gas X. This can be expressed mathematically as:
\[
\text{Rate of CH}_4 = 2 \times \text{Rate of gas X}
