  1. Chapter 11b Ideal Gas Laws

  2. When pressure, volume, and temperature are known, the ideal gas law can be used to calculate • molar amount

  3. Calculate the approximate volume of a 0.600 mol sample of gas at 15.0°C and a pressure of 1.10 atm • V = nRT • P • 0.600mol * 0.0821 (15.0°C +273) = 12.9 L • 1.10 atm

  4. True or false • John Dalton developed the concept that the total pressure of a mixture of gases is the sum of their partial pressures? True

  5. Who developed the Law that states that equal volumes of gas at the same pressure and temp. contain equal numbers of moles.? Avogadro

  6. If a gas with an odor is released in a room, it quickly can be detected across the room because it • diffuses

  7. True or false • The law of combining volumes applies only to gas volumes measured at constant temperature and pressure. True

  8. the odor of perfume spreading throughout a room is an example of gas diffusion

  9. A 1.00 L sample of a gas has a mass of 1.92 g at STP. What is the molar mass of the gas? molar mass = grams * RT PV 1.92g * 0.0821 * (273K) = = 43.0g/mol 1.00 atm* 1.00 L

  10. If two gases are both measured at 725 ˚C and 5.05 atm, what volume of N2 (g) can be produced from the decomposition of 37.6 L of NH3 (g)? 37.6 L Avogadro’s law: equal volumes of gas contain equal numbers of moles at the same pressure and temp.

  11. Knowing the mass and volume of a gas at STP allows one to calculate the

  12. The principle that under similar pressures and temperatures, equal volumes of gases contain the same number of molecules is attributed to Avogadro
