Sheet1 Page 1 Charles' Law: (V-T(emperature)) relationship) The volume of a fixed quantity of gas at a constant pressure is directly proportional to its absolute temperature V/T = K K = Constant **V1/T1 = V2/T2 V = Volume T = Temperature --- Avogadro's Law: (Volume - Number of Mol(n) relationship) The volume of a fixed quantity of gas at constant temperature and constant pressure is directly propotional to the number of m o v/n = K K = Constant **V1/n1 = V2/n2 --- Ideal Gas Law: Add these together: V = K Tn \ P = RTn \ P K = All constants in three laws R = K **PV = nRT (Ideal gas equation)

Unformatted text preview: **R = Ideal Gas Constant **R = 0.08206 L atm / K mol **if using ideal gas constant, you must convert volume to litres, pressure to atm--An ideal gas is present in a cylinder of volume 5.0 x 10^2mL at 30.00*C with a pressure of 710Torr. The gas is compressed to Calculate the new pressure Sheet1 Page 2--Molar Mass and Density MM = dRT / PV Molar Mass / Empirical Formula = take closest whole number i.e. CH2---Gas stoichiometry Reactions involving gas evolution, mass, temperature, pressure, mol (ideal gas equation). Molar Volume The volume one mol of any idea gas will occupy at 0*C and 1atm pressure (STP). Molar volume = 22.42L---...
