Gas Laws

Gas Laws

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
  2. Then use 22.4mol=1L
3. Mass-Volume (Non-STP)
  1. Use the proportions in chemical equations
  2. Varied number of steps.
Combined Gas Laws
1. P1V1/T1=P2V2/T2
2. Charles' Law
  1. V1/T1=V2/T2
  2. Fixed pressure, temp/volume direct relationship
3. Boyle's Law
  1. P1V1=P2V2
  2. Fixed temp, volume/pressure inverse relationship.
4. Gay Lussac's Law
  1. P1/T1=P2/T2
  2. Fixed volume, temp/pressure direct relationship.
5. Combines Boyle's, Charles', and Gay Lussac's Laws.
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
2. Pt=P1+P2+P3....
3. Partial Pressure over Water
  1. P(t)=P(g)+P(h2o)
Ideal Gas Law
1. PV=nRT
  1. R=0.0821Latm/molK
2. PV/nT=R
  1. R=8.31kPadm^3/molK
3. For ideal gasses: PV/T and the number of moles is equal to a constant.
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.
2. D1/D2=(squrt)M1/M2
