  1. Chapter 19 The Ideal Gas Equation

  2. The Ideal Gas Equation PV=nRT

  3. Ideal-Gas Equation PV = nRT • P = pressure • V = volume • n = number of moles • T = temperature • R = gas constant

  4. R values a A I

  5. How many moles of gas will a 1250 cm3 flask hold at 35.0C and a pressure of 95.4 kPa? 0.0466 mol

  6. What pressure in kPa is exerted by 0.00306mol of gas in a 25.9cm3 container at 9.0°C? 277 kPa

  7. The Concorde, a supersonic passenger jet flew its last flight on November 26, 2003. It was a major pollution concern in that it produced 6.6 x 104 kg of CO2 for each hour of flight at 42 kPa and 627°C. How many liters of CO2 is this?

  8. The Concorde, a supersonic passenger jet flew its last flight on November 26, 2003. It was a major pollution concern in that it produced 6.6 x 104 kg of CO2 for each hour of flight at 42 kPa and 627°C. How many liters of CO2 is this? 2.67 x 108 L = 267,000,000 L

  9. Gram Formula Mass (Molar Mass) • The ratio of grams per mole. H2 = 2 g/mol CO2 = 44 g/mol H2O = 18 g/mol

  10. A poisonous gas is leaking out of an old gold mine. A chemist uses the ideal gas equation to determine that 4.564 grams of the gas are equivalent to 0.163 moles. Is the gas CH2, CO, or AsH3

  11. 0.186 g of a gas at 35.0C and 95.4 kPa occupies a volume of 1250 cm3. Is the gas H2, He, O2, or CO2?

  12. 1.00g of a gas occupies 0.820 dm3 at 760 torr and 3.0°C. The gas is most likely: (a) BH3 (b) B4H10 (c) B2H6 (d) B3H12 (e) B5H14
