when do u use avogadros number
moles and # of particles
unit for molar mass
g/mol
atomic mass unit
amu
molar mass is
adding atomic masses of component atoms
mass % of element equation
= # of atoms of that element times molar mass of that element all divided by molar mass of compound times 100%
empirical formula
formulas reduced or simplified as much as they can be
molecular formula
actual formula that cannot be simplified and often many empirical formulas
percent yield
= actual yield divided by theoretical yield x 100
theoretical yield is
amount of product predicted from stoichiometry taking LR into consideration
actual yield is
amount of product actually obtained in reaction
percent yield
compared the actual field to the theoretical yield to gage the viability of a lab experiment
