Because there are no compounds that aren't molecules/molecular. The question as posed is nonsense. Rephrase?
Because unlike the empirical formula, the molecular formula does not have to be the simplest ratio.If by chance you are given the percent composition of the elements in a substance, you could calculate the empirical formula and then the empirical formula's mass. However, the molecular formula equation is molecular formula= (empirical formula)n, where n is the mass of the molecular formula divided by the mass of the empirical formula. You would, therefore, need to know the mass belonging to the molecular formula, which you are not given.
Compounds having this molecular formula are organic compounds.
isomers
Yes, isomers are compounds that have the same molecular formula but different structural arrangements or spatial orientations of their atoms.
This molecular formula is C9H12.
molecular formula
it is not a molecule
Ammonia and nitrogen are two distinct compounds, not a single compound that would have a molecular formula.
Isomers.

Molecular formulas that are also empirical formulas include compounds like water (H2O), methane (CH4), and hydrogen peroxide (H2O2). In these cases, the molecular formula is the same as the empirical formula because the compounds consist of only one type of atom.
Two compounds that have the same molecular formula but different structural formulas are isomers. Isomers are compounds with the same number and types of atoms but arranged differently. An example is ethanol (C2H6O) and dimethyl ether (C2H6O), both have the same molecular formula but different structural formulas.
Compounds having this molecular formula are organic compounds.
CH2O is not only the empirical but also the molecular formula for formaldehye. It is also the empirical but not the molecular formula for hydroxyacetaldehyde, acetic acid, methyl formate, 1,3-dihydroxyacetone, and many other compounds.
The molecular formula for silver nitrate is AgNO3.This white solid is often used as a precursor to many other silver compounds.
