  1. Ideal Gas Law

  2. What is an ideal gas? • Doesn’t have any intermolecular forces of attraction. • Have elastic collisions. • Mass and size of the gas particles are irrelevant What is the ideal gas law? • The mathematical relationship among pressure, volume, temperature and the number of moles of a gas

  3. Ideal Gas Law Pressure Must be in Atmospheres (atm) Temperature Must be in Kelvin (K) Moles MOLE HIGHWAY!! Volume Must be in Liters (L) Gas Constant 0.0821

  4. Ideal Gas Law • What is the pressure exerted by a 0.500 mol sample of nitrogen gas in a 10.0 L container at 298 K? • P = x • V = 10.0 L • n = 0.500 mol • R = .0821 • T = 298 K

  5. Ideal Gas Law • What is the volume of 105 g of chlorine gas, Cl2, at 27°C and 3.50 atm? • P = 3.50 atm • V = x • n = 105 g • R = .0821 • T = 27°C

  6. Ideal Gas Law • How many grams of carbon dioxide gas are there in a 45.1 L container at 34°C and 790. mmHg? • P = 790. mmHg • V = 45.1 L • n = x • R = .0821 • T = 34°C

  7. Ideal Gas Law • What is the volume of 1 mol of gas at STP? • P = 1 atm • V = x • n = 1 mol • R = .0821 • T = 0°C
