The Mole
11.1 Measuring Matter
counting particles, Avogadro’s Number 6.02 x 10 ^{23}, mole,
 mole ↔ particle equations
 # moles x 6.022 x 10^{23} particles/mole = # of particles
 # particles x 1 mole / 6.022 x 10^{23} particles = # of moles
11.2 Mass and the Mole
mass of a mole, molar mass,
 mass ↔ mole equations
 # of moles x # of grams / mole = # of grams
 mass (in grams) / molar mass (grams / mole) = # of moles
11.3 Moles of Compounds
chem formulas & mole, molar mass of compounds,
mole ↔ mass of compound
mass ↔ particles (molecules) of compound
11.4 Empirical and Molecular Formulas
Percent composition of compound, empirical formula, determining molecular formula
% by Mass = Mass of Element / Mass of Compound x 100
11.5 Formula of a Hydrate
Naming hydrates Na_{2}CO_{3} · 10 H_{2}O is a decahydrate (10 waters per molecule)
Empirical formula, molecular formula
Molecular formula = (empirical formula subscripts) n
