1. Dalton's Gas Law
Total pressure of a mixture of gaes equals the sum of the pressures that each gas would exert if it was present alone

Pt=P1+P2+P3...
2. Avogardro's Law
If you have the same volume of 2 gases, they'll have the same number of molecules
6.022 x 1023 # of particles in a molecule
4. Boyle's Law
Volume is inversely propotionate to pressure; If volume is down pressure is up

P1V1 = P2V2
5. Charle's Law
Directly proportions: As volume goes up, tempreture goes up

V1/T1 = V2/T2
6. Gay-Lussac's
Direct proportions: If pressure goes up, temperture goes up

P1/T1 = P2/T2
7. The Combined Gas Law
Charles and Boyles Law

(P1V1)/T1 = (P2V2)/T2
8. Ideal Gas Law
PV = nRT
9. Conversion of Celcius to Kelvin
Celcius + 237 = K
10. Constant for R
0.0821 L(atm)/mol(K)
11. Grahams Law
Rate of diffusion is inversly proportionate to the square root of molecular mass

• Rate A/Rate B
• = Sq root of Molecular mass of B/Sq Root of Molecular mass of A
