0.64 g of an oxide of sulphur occupies 0.224 L at 2 bar and `273^(@)C`. Identify the compound. Also find out the mass of one molecule of the gas.

Explanation

To solve the problem of identifying the oxide of sulfur and finding the mass of one molecule of the gas, we can follow these steps:

### Step 1: Use the Ideal Gas Law
The ideal gas law is given by the equation:
\[ PV = nRT \]
Where:
- \( P \) = pressure (in bar)
- \( V \) = volume (in liters)
