Empirical
formula
use with page 344.
explain empirical formula by completing the following statements.
to determine the empirical for a compound, you must first
determine the smallest whale number ratio of the moles of the elements in
the compound. this ratio provides the in the empirical formula
if the empirical formula differs from the molecular formula, the molecular
formula will be a multiple of the empirical formula. the data used to
determine the chemical formula may be in the form of
or it may be the actual masses. when the percent composition is given, you
can assume that the total mass of the compound is 100.0 g to simplify
calculations. the of elements in a compound must be_
whole numbers to be used as
in the chemical formula.
