the simplest whole number ratio of atoms in a compound
how to convert to empirical
convert whats given to mols (% →) g→mol
divide by smallest mole number to find whole number ratio
use ratio for subscripts
Molecular formula
actual number of each type of atom present, ratio of empirical formula
Stoichiometry
the coefficients of a balanced chemical equation reveal the ratio of numbers of moles of reactants used to the number of moles of products made.
Stoich of gasses with same T and P
since equal number of products, can shortcut, coefficients directly give gas vol ratios as well as mol ratios
Stoich gasses not at stp
must use ideal gas law (PV = nRT)
Percent yield
(Experimental/Theoretical) * 100
What is the excess reactant
the reactant of which there will be an excess after reaction
What is the limiting reactant
the reactant that will be fully used up in a chemical equation
