It tells you what the substance is made of.
Not completely. The empirical formula of a substance can be determined from its percent composition, but a determination of molecular weight is needed to decide which multiple of the empirical formula represents the molecular formula.
The chemical formula is determined by chemical analysis of the components.
Sulfur is an element, a pure substance, it is 100% sulfur.
A substance has a specific chemical composition while mixtures contain more than one substance.
A pure substance has a fixed and uniform composition.
