  7. Gases: Ideal Gas Law Dr. Chu River Dell Regional High School

  8. Ideal Gases • Gas molecules are far apart so the volume each gas molecule occupies is negligible compared to the volume the gas occupies. • Gas molecules do not interact with each other. • All collisions between gas molecules and walls of the container are elastic, meaning no energy loss in the form of heat during collision.

  9. Ideal gas law

  10. Ideal gas law

  11. Ideal gas law

  12. Ideal gasLaw - Example • For 4 moles of a gas at a pressure of 5.6 atm and a volume of 12 liters, what is the temperature?

  13. Ideal gasLaw - Example • What volume would 32.0 g of NO2 gas occupy at 3.12 atm and 18.0°C?

  14. Ideal gasLaw - Example • Determine the density of CO2 at 745 mmHg and 65oC?

  15. Ideal Gas laws – exercise • At what temperature does 16.3 g of nitrogen gas have a pressure of 1.25atm in a 25.0 L tank?? • Calculate the molecular weight of a gas if 35.44 g of the gas stored in a 7.50 L tank that exerts a pressure of 60.0 atm at a constant temperature of 35.5°C. • An unknown gas has a density of 3.167 g/L at STP. What is the identity of the gas? (Ar, O2, Cl2, HF, H2O)?

  16. Ideal Gas laws – exercise (answers) • At what temperature does 16.3 g of nitrogen gas have a pressure of 1.25atm in a 25.0 L tank?? • Calculate the molecular weight of a gas if 35.44 g of the gas stored in a 7.50 L tank that exerts a pressure of 60.0 atm at a constant temperature of 35.5°C. • An unknown gas has a density of 3.167 g/L at STP. What is the identity of the gas? (Ar, O2, Cl2, HF, H2O)?
