Gas Laws: Ideal Gas Law Law::

PV = nRT

R = 0.0821 L*atm/mol*K Combined Gas Law:

P1V1 = P2V2 T1 T2

Dalton’s Law of Partial

Pressures:

Ptot = Pa + Pb + Pc …

Graham’s Law:

Solutions: Molarity = mol solute L solution Freezing point change: Boiling point change:

Molality = mol solute kg solvent  ΔT = Kf*m*i  ΔT = Kb*m*i

Dilution/Titration formula:

Acids/Bases: +

pH = -log [H ] pOH = -log [OH ] pH + pOH = 14

M1V1 = M2V2
