⇒Thus, empirical formula is CH2O. Q.

If you are studying a chemical compound, you may want to find the percent composition of a certain element within that chemical compound. The equation for percent composition is (mass of element/molecular mass) x 100.

A sample of an unknown compound with a mass of 0.847g has the following composition: 50.51% fluorine and 49.49% iron.

%C=40.8⋅g95.2⋅g×100%=42.9% . %O=54.4⋅g95.2⋅g×100%=57.1% .

Therefore, the empirical formula of the compound is S 3 O 4 . Q. What is the Empirical formula of a compound with 40% sulfur and 60% oxygen by mass?
