Chemistry Practice Problems: The Gas Laws
Solve the following gas law problems. Make sure to include units in your answer. Tell which law was used to solve each one.
- A sample of O2 gas occupies a volume of 2.00 L at 27 ˚C and 2.00 atm pressure. What volume, in liters, will this O2 sample occupy at the same temperature but at 3.2 atm?
Answer: ______Law: ______
- A sample of air exerts a pressure of 1.00 atm at 22C. If the sample's volume remains constant, what is the new pressure, in atmospheres, exerted by the air when it is heated to 122C?
Answer: ______Law: ______
- 5.00 L of a gas is known to contain 0.965 mol. If the amount of gas is increased to 1.80 mol, what new volume will result (at an unchanged temperature and pressure)?
Answer: ______Law: ______
- A spray can is empty except for the propellant gas, which exerts a pressure of 1.2 atm at 24C. If the can is thrown into a fire (485C), what will be the pressure, in atmospheres, inside the hot can?
Answer: ______Law: ______
- A sample of carbon dioxide gas, CO2, has a volume of 5.00 L at 35C. What volume, in liters, will this CO2 gas occupy at 125C if the pressure is held constant?
