The Ideal Gas Law No gas perfectly obeys all of the gas laws under all conditions. Nevertheless, these assumptions work well for most gases and most conditions.
  There is a relationship between volume and the number of moles of a gas  V = kn  V/n = k  Volume is directly proportional to the number.

Gas volumes and moles PAGE 87 OF INB

Essential Question:  How can 2 liters of Hydrogen react with 1 liter of Oxygen and only produce 2 liters of gas?

Measuring Volumes  Gay-Lussac law of combining volumes of STP, the volume of gaseous reactants and products can be expressed as ratios of small whole numbers.  Avogadro's Law: Equal volumes of gases at the same temperature and pressure contain an equal number of particles.  V = Kn (K is a constant and n is amount of gas)  H 2(g) + O 2(g) = H 2 0 (g)

Volume to Moles:  Standard molar value of a gas: 22.4 L = 1
