Chem Final Study Guide Avogadro’s Number = 6.02 x 10^23 (molecules/mole constant) used to find number of molecules Molecular Concentration = Moles/Liter = Molarity. Moles = (Grams)/(Grams per Mole) Density = Mass/Volume (An element weighs X grams/Mole – this can be used to find volume and density) Percent Mass by composition of CO2 (Mass of Carbon/Mass of Carbon + 2 Oxygen) MF2 – Results in three ions in solution. NaCl – Results in two ions in solution Percent Yield (Actual Yield/Theoretical Yield) REDOX 1. Balance Molecules by adding water to sides. 2. Balance charge by adding electrons to sides. 3. If basic solution, add OH- to remove the H+. 760 torr or mm Hg = 1.01325mbar = 1atm PV/T = PV/T’ PV = nRT (R = .08206) Bomb Calorimitry: Qcal = Ccal x T Antoine Lavioser – Law of conservation of mass Joseph Proust – Law of constant composition/ law of definite proportions John Dalton – Atomic theory, led to the law of multiple proportions Michael Farady – cathode ray tube experiment, discovered electron
