The volume of a gas X and chlorine diffusing during the same time and through same holes are 25mL and 29mL, respectively. If molecular mass of chlorine is 71, calculate the molecular mass of gas X.

Explanation

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

### Step-by-Step Solution:

1. **Identify the Given Data:**
- Volume of gas X (V1) = 25 mL
- Volume of chlorine (V2) = 29 mL
- Molecular mass of chlorine (M2) = 71 g/mol
