What volume will a sample of gas occupy at `87^(@)C` and `720 mm` pressure if its volume at `27^(@)C` and `750 mm` pressure is `250 mL` ?

Explanation

To find the volume of a gas sample at a new temperature and pressure, we can use the combined gas law, which relates the pressure, volume, and temperature of a gas. The formula is:

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