IDEAL GAS LAWS

• • describes the physical behavior of an ideal gas in terms of pressure, volume, temp, and number of moles
• • the combination of all 4 gas laws from the previous sections
• EQUATIONS

  ideal gas law

  PV = nRT

  molar mass & ideal gas law

  MPV = mRT

  density & ideal gas law

  MP = dRT
• gas density at STP

  • density if gas at STP is constant, due to the standard molar volume of a gas
  • density (STP) = molar mass / molar volume
• • non-STP
  • density of gas changes with temp and pressure, due to volume of equation (must use ideal gas law)
  • density = mass / volume 
• rates of ideal gas constants

  • 0.0821 atm
  • 62.4 mmHg
  • 8.314 kPa
• U MUST HAVE KELVINS AND LITERS FOR UR RATES OR ELSE IT WILL NOT WORK
