A sample of argon gas occupies \(0.500 \mathrm{~L}\) at \(-125^{\circ} \mathrm{C}\) and \(225 \mathrm{~mm}\) Hg. Calculate the pressure in \(\mathrm{mm} \mathrm{Hg}\) if the gas occupies \(0.375 \mathrm{~L}\) at \(100^{\circ} \mathrm{C}\).

A sample of xenon gas occupies \(500.0 \mathrm{~mL}\) at \(-185^{\circ} \mathrm{C}\) and \(75.0 \mathrm{~cm} \mathrm{Hg} .\) Calculate the Celsius temperature if the volume is \(225.0 \mathrm{~mL}\) at \(55.0 \mathrm{~cm} \mathrm{Hg}\).

Which of the following liquids has the higher vapor pressure at \(25^{\circ} \mathrm{C}:\) water or mercury?

Air contains nitrogen, oxygen, argon, and trace gases. If the partial pressure of nitrogen is \(592 \mathrm{~mm} \mathrm{Hg}\), oxygen is \(160 \mathrm{~mm} \mathrm{Hg}\), argon is \(7 \mathrm{~mm} \mathrm{Hg}\), and trace gas is \(1 \mathrm{~mm} \mathrm{Hg}\), what is the atmospheric pressure?
