(Calculation of the empirical formula from mass data.)
Empirical Formula: The simplest ratio of the atoms present in a molecule.
Find the empirical formula for the oxide that contains 42.05 g of nitrogen and 95.95 g of oxygen.
As with most stoichiometry problems, it is necessary to work
in moles. The ratio of the moles of each element will provide the
ratio of the atoms of each element.
