To find the pressure of a sample of hydrogen chloride gas that is 0.125 L at 30 °C, we can use the ideal gas law. The initial volume and temperature of the gas are 1.00 L and 273.15 K, respectively. The final volume and temperature of the gas are 0.125 L and 303.15 K, respectively. Substituting these values into the ideal gas law, we find that the final pressure of the gas is approximately 8.86 atm.
