### Chapter 11: The Mole

11.1 Measuring Matter
counting particles, Avogadro’s Number 6.02 x 1023, mole,
mole ↔ particle equations
# moles x 6.022 x 1023 particles/mole = # of particles
# particles x 1 mole / 6.022 x 1023 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 Na2CO3 · 10 H2O is a decahydrate (10 waters per molecule) Empirical formula, molecular formula Molecular formula = (empirical formula subscripts) n
