A mixture of `N_(2)` and a gas 'X' at 300K, is allowed to diffused into empty container of 5.0 L volume. The pressure inside the vessel recorded as 5.5 atm. If 0.9 moles of `N_(2)` is present in the mixture then calculate molecular mass of 'X'

Explanation

To solve the problem, we will follow these steps:

### Step 1: Use the Ideal Gas Law
We start with the Ideal Gas Law, which states:
\[ PV = nRT \]
Where:
- \( P \) = total pressure (5.5 atm)
- \( V \) = volume (5.0 L)
