Stepwise Gas Law Solutions
Moles of gas are constant in Ch. G

  1. Read the problem.
  2. List all temperatures, pressures and volumes with the units as given.
  3. Identify what the problem wants (V, T or P) and state the units wanted.
  4. If V, T, or P are held constant, write that down.
  5. Change temperature into kelvins.
  6. Convert all pressure units to the same units.
  7. Convert all volume units to the same units.
  8. Plug all these values (or ? for what is wanted) into the Initial/Final Table.
  9. Solve the Combined Gas Law for what you want.

This sounds rather complicated, and does force you do do a little algebra to solve the combined gas law, but it will work every time.
