1. What is the final volume of argon gas if 2.50 L at 705 torr is compressed to a pressure of 1550 torr? Assume the temperature remains constant.
2. Calculate the volume of chlorine gas at 20°C and 75.0 cm Hg if the volume of the gas is 1.10 L at 20°C and 95.5 cm Hg.
Charles' Law:
3. What is the final Celsius temperature if 4.50 L of nitric oxide gas at 35°C is cooled until the volume reaches 1.00 L? Assume the pressure remains constant.
Gay-Lussac's Law:
4. A sample of xenon gas at 20°C and 0.550 atm is cooled to a pressure of 0.100 atm. If the volume remains constant, what is the final Celsius temperature?
Combined Gas Law:
