Gas Laws
  1. Stoichiometry
    1. Volume-Volume
      1. Problems Involving the volumes of both known and unknown quantities
      2. Mixed Mass-Volume-Mole-Particle
        1. Find the unknown at STP
          1. Then use 22.4mol=1L
          2. Mass-Volume (Non-STP)
            1. Use the proportions in chemical equations
              1. Varied number of steps.
            2. Combined Gas Laws
              1. P1V1/T1=P2V2/T2
                1. Charles' Law
                  1. V1/T1=V2/T2
                    1. Fixed pressure, temp/volume direct relationship
                    2. Boyle's Law
                      1. P1V1=P2V2
                        1. Fixed temp, volume/pressure inverse relationship.
                        2. Gay Lussac's Law
                          1. P1/T1=P2/T2
                            1. Fixed volume, temp/pressure direct relationship.
                            2. Combines Boyle's, Charles', and Gay Lussac's Laws.
                            3. Dalton's Law of Partial Pressures
                              1. Total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gasses
                                1. Pt=P1+P2+P3....
                                  1. Partial Pressure over Water
                                    1. P(t)=P(g)+P(h2o)
                                  2. Ideal Gas Law
                                    1. PV=nRT
                                      1. R=0.0821Latm/molK
                                      2. PV/nT=R
                                        1. R=8.31kPadm^3/molK
                                        2. For ideal gasses: PV/T and the number of moles is equal to a constant.
                                        3. Graham's Law of Diffusion
                                          1. Under the same conditions of T and P, gasses diffuse at rates that are inversely proportional to the square root of their densities.
                                            1. D1/D2=(squrt)M1/M2
