Avogadro’s number
the number of particles (6.022 x 10^23) of a substance in 1 mol of
that substance. By definition, Avogadro’s number is equal to the
number of carbon-12 atoms in exactly 12.00 g of carbon-12.
balanced
appropriate coefficients have been added such that the number
of atoms of each element are the same in both reactants and
products.
chemical equation
a precise quantitative description of a reaction.
coefficients

the number placed in front of the substance in a chemical
equation that reflect the specific numbers of units of those
substances required to balance the equation.
formula mass
the total mass of all the atoms present in the formula of an ionic
compound, in atomic mass units (amu), or the mass of one mole
of formula units in grams per mole.
limiting reagant
the reactant that is consumed first, causing the reaction to
cease despite the fact that the other reactants remain “in
excess.” Also known as the limiting reactant.
mass percent
the percent of a component by mass. mass % = (total mass
component/total mass whole sub.) x 100%

mole
the quantity represented by 6.022 x 10^23 particles.
molecular mass
the mass of one molecule, expressed in atomic mass units
(amu), or the mass of one mole of molecules in grams per mole.
percentage yield
the actual yield of a reaction divided by the theoretical yield and
then multiplied by 100%.
phase
a part of matter that is chemically and physically homogeneous.
