The volume of a gas X and chlorine diffusing during the same time are 35 mL and 29 mL respectively. If molecular mass of chlorine is 71, calculate the molecular mass of gas X.

Explanation

To solve the problem of finding the molecular mass of gas X using Graham's law of effusion, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Graham's Law**:
Graham's law states that the rate of diffusion of a gas is inversely proportional to the square root of its molar mass. The formula is given by:
\[
\frac{R_1}{R_2} = \sqrt{\frac{M_2}{M_1}}
