Avogadro’s # = 6.022 x 10 23 1 mL = 1 cm 3 Kelvins = C + 273.15 F = 9/5 x C +32 C = 5/9 (F – 32) Ionic Equation shows break down of compounds – polyatomics are together. Net Ionic cancels out some (spectators) to show precipitate and both reactants only. % comp. = # moles x molar mass of element x 100 Molar mass of compound Unknown-Find the % comp. of element in known compound. Take %, convert to 0. and multiply by given mass of known compound. Take that # & plug it for numerator into % comp formula with given unknown’s mass on bottom. Molarity = moles of solute Liters of solution Titration- Whatever element needs concent. found, convert the given grams to mol. Than # goes in numerator in molarity equation. Mol/L = M MiVi = MfVf Bronsted acid- proton donor NH 4 + ammonium H 2 PO 3-dihydrogen phosphite H 3 O + hydronium H 2 PO 4-dihydrogen phosphate Hg 2 2+ mercury(I) HCO 3-hydrogen carbonate CNO-cyanate HSO 3-hydrogen sulfite CNS-thiocyanate HSO 4-hydrogen sulfate MnO 4-
