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.
molecular formula is referred to water because they are covalent compounds while formula mass for aluminum chloride because they are ionic compounds
NaBr would be a formula unit as all sodium (Na) compounds are ionic.
isomers
molecular formula
Isomers.
it is not a molecule
Ammonia and nitrogen are two distinct compounds, not a single compound that would have a molecular formula.
Two compounds that have the same molecular formula but different structural formulas are isomers of each other.
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.

Sort of, though the term "chemical formula" is more accurate for describing compound molecular or otherwise.

Molecular compounds are formed between two ionic bonds
