A certain quantity of a gas measured 500 mL at a temperature of `15^@C` and 750 mm Hg What pressure is required to compress this quantity of gas into a 400 mL vessel at a temperature of `50^@C` ?

Explanation

To solve the problem, we will use the combined gas law, which is derived from the ideal gas law. The combined gas law states that:

\[ \frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2} \]

Where:
- \(P_1\) = initial pressure
