  1. Unit 13 Gas Laws Test Review The Ladder Game

  2. Rules: • Pick one question to do from the set (1 question per team member) • Once you finish your question, pass your paper back to your teammate for them to pick a question. • If you are the last person in the row, you must check your team’s work. • When you are finished, run your paper back to the front!

  3. Round 1 • What does it mean for two variables to be inversely related? • What is an example of two variables from this unit which are inversely related? • What does STP stand for? • What are the two values associated with STP?

  4. Round 2: Gas Law Problems • A sample of gas has an initial pressure of 2.5 atm and a volume of 15 mL. What would the pressure be when the volume is 30 mL? • Convert 1.75 atm to kPa and mm Hg. (2 answers needed!) • At 12°C, a balloon has a volume of 1.20 L. What is the volume of the balloon at 25°C? • A sealed canister is originally at 150 kPa and 25°C. If this canister is stored at 47°C, what would the new pressure inside the canister be?

  5. Round 3: Gas Law Problems • Convert 156 mL to liters. • A bubble has a volume of 0.13 mL at 15 atm. What is the volume of the bubble at 994 kPa of pressure? • A sample of gas has a volume of 150 mL at 1.23 atm and 25°C. What is the pressure of the gas (in mmHg) at a volume of 75 mL and a temperature of 35°C? • Convert 0.234 atm to mmHg.

  6. Round 4: Ideal Gas Law • What is the ideal gas law formula? • A 0.245 mol sample of gas has a volume of 2.1 L at 298 K. What is the pressure of the gas under these conditions? • How many moles are in a 115 mL sample of oxygen gas at 23°C and 1.13 atm. • What units are required for pressure, volume, and temperature when using the ideal gas law?

  7. Round 5: Ideal Gas Law • What volume will a 1.45 mol sample of gas take up at a pressure of 440 mmHg and a temperature of 37°C? • What is the molar mass of H2S? • At what temperature will 12.2 grams of O2 gas be at a volume of 345 mL and a pressure of 0.765 atm? • How many grams are in a 2 L sample of CO2 gas at 35°C and 0.432 atm?
