5. Ten (10.0) liters of hydrogen gas under a 3.50 atm of pressure is contained in a cylinder with a
movable piston. The piston is moved until the gas occupies only 3.00 L. What is the pressure of the
cylinder?
6. A sample of gas at 25.0 °C occupies 100.0 mL at atmospheric pressure, 760. mmHg. If the pressure
increased to 850. mmHg, what will be the new volume of the gas?
