A certain mass of a gas taken in 1 L cylinder exerts a pressure of 500 mm Hg at a certain temperature. If the gas is transferred to another cylinder where it exerts 20 per cent more pressure, calculate the volume of the cylinder at the same temperature.

Explanation

To solve the problem, we will use the relationship between pressure and volume of a gas at constant temperature, which is derived from Boyle's Law. The formula we will use is:

\[ P_1 V_1 = P_2 V_2 \]

### Step-by-Step Solution:

1. **Identify the given values:**
- Initial pressure \( P_1 = 500 \, \text{mm Hg} \)
