Combustion of adipic acid yields percentage abundances of #C:49.3%#, #H:6.9%#, and #O:43.8%#. What are the empirical and molecular formulae of adipic acid?
Adipic acid has a molecular formula of
As with all problems of this type, we assume a quantity of
We divide thru by the smallest molar quantity, that of oxygen, to get the empirical formula of
Now, the molecular formula is some whole number ratio of the empirical formula:
So we have to simply solve for
