A bulb A containing gas at 1.5 bar pressure was connected to an evacuated vessel of 1.0 `dm^(3)` capacity through a stopcock. The final pressure of the system dropped to 920 mbar at the same temperature. What is the volume of the container A?

Explanation

To solve the problem step by step, we will use the ideal gas law and the relationship between pressure and volume when the temperature remains constant.

### Step 1: Note down the given values
- Initial pressure in bulb A, \( P_1 = 1.5 \, \text{bar} \)
- Volume of the evacuated vessel, \( V_1 = 1.0 \, \text{dm}^3 = 1.0 \, \text{L} \)
- Final pressure of the system, \( P_2 = 920 \, \text{mbar} = 0.920 \, \text{bar} \)

### Step 2: Understand the final volume
