A formula unit is an empirical formula.
the empirical formula of a compound tells you the proportions of the elements in the compound. with that information you can make some inferences about the identity of the compound. for example a compound with an empirical formula CH4 tells us that for every carbon atom there are four hydrogen atoms. this means that the compound is methane because no other hydrocarbon can have these roportions (try drawing the lewis structure for C2H8, which doesnt exist. you cant!)
A molecular formula is identical to the empirical formula, and is based on quantity of atoms of each type in the compound.The relationship between empirical and molecular formula is that the empirical formula is the simplest formula, and the molecular can be the same as the empirical, or some multiple of it. An example might be an empirical formula of C3H8. Its molecular formula may be C3H8 , C6H16, C9H24, etc. Looking at it the other way, if the molecular formula is C6H12O6, the empirical formula would be CH2O.

They would form an ionic compound.
the molecular mass of a compound and its empirical formula
No. The empirical formula of a substance is the formula in which each atomic symbol has the lowest possible subscript that gives the correct ratio between atoms for the compound as a whole. For C6H12, the empirical formula is CH2, but for C6H14, the empirical formula is C3H7.

The empirical formula of a compound shows the lowest whole number ratio of the elements in that compound; AKA simplest formula. The molecular formula describes the number of atoms of each element that make up the molecule or formula unit; AKA actual formula
Potassium sulfide is K2S.
A formula unit includes the correct number of each kind of atoms present in a molecule of a covalently bonded compound, but an empirical formula does not necessarily do so. An empirical formula is reliable with respect to the ratios between each kind of atom, but the molecule may contain any positive integral number of empirical formulas, including one.
