A gas occupies a volume of 250 mL at 745 mm Hg and `25^(@)C`. What additional pressure is required to reduce the gas volume to 200 mL at the same temperature?

Explanation

To solve the problem step by step, we will use the Ideal Gas Law and the concept of pressure and volume relationships.

### Step 1: Identify the given values
- Initial volume (V1) = 250 mL
- Initial pressure (P1) = 745 mm Hg
- Final volume (V2) = 200 mL
- Temperature (T) = 25°C = 298 K (since T in Kelvin = T in °C + 273)
