CFI Chemistry Gas Laws

Total pressure of a mixture of gaes equals the sum of the pressures that each gas would exert if it was present alone

P_t=P₁+P₂+P₃...

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

Volume is inversely propotionate to pressure; If volume is down pressure is up

P₁V₁ = P₂V₂

Directly proportions: As volume goes up, tempreture goes up

V₁/T₁ = V₂/T₂

Direct proportions: If pressure goes up, temperture goes up

P₁/T₁ = P₂/T₂

Charles and Boyles Law

(P₁V₁)/T₁ = (P₂V₂)/T₂

PV = nRT

Celcius + 237 = K

0.0821 L(atm)/mol(K)

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
