  1. What is the Graham's law?
    [rate A/rate B]= [aw B/aw A]1/2
  2. With Graham's law, instead of being given rates you are given the same time; what's the formula?
    [d A/ d B] = [aw B/aw A]1/2
  3. With Graham's law, instead of being given rates you are given the same distance; what's the formula?
    [t B/ tA]= [aw B/aw A]1/2
  4. What is the ideal gas law?
  5. Name the combined gas law.
  6. What is Dalton's law?
