Types of Chemical Reactions and Solution Stoichiometry

Determining Molarity: http://cdn-1.learnchem.net/formula/1.gif (411 bytes)

Molarity and Volume:
(M1 is the molarity of solution one, which has a volume of V1. M2 is the molarity of solution two, which has a volume of V2.)
M1V1 = M2V2

Gas Laws

The Ideal Gas Law:
(P = pressure in atm, V = volume in liters, n = moles, R = 0.082058 L*atm/mol*K, T = temperature in Kelvins)
PV = nRT

Boyle's Law:PV = K

Charles Law:K = V/T

Derivative of the Ideal Gas Law:
(MW = molecular weight, d = density)
MW = dRT / P

Root Mean Square:
(R = 8.3145 J/ K * mol, M = mass of a mole of the gas in kg)
