The molecular formula may be a multiple of the empirical formula.
The empirical formula is similar.
What you write for an ionic compound is called the formula unit, but the formula unit is almost always the same as the empirical formula. The answer to your question could not be the molecular formula because an ionic compound is not a molecule.
No, compounds with the same empirical formula can have different molecular formulas. This is because the empirical formula gives the simplest whole-number ratio of atoms in a compound, while the molecular formula gives the actual number of each type of atom in a molecule.
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.

No, Compounds with the same empirical formula have the same elements in the same ratio. SO2 and CO2 contain different elements. SO2 is a compound of sulfur and oxygen while CO2 is a compound of carbon and oxygen.
Isomerism. The structures of the molecules are different even when the numbers of atoms are the same. Organic molecules are the most common examples of this. Compare n-butane and iso-butane same formula different structures. See link

Yes, it is possible for different covalent compounds to have the same empirical formula. This occurs when compounds have different arrangements of atoms but the same ratio of elements. An example is ethyne (C2H2) and benzene (C6H6), both of which have an empirical formula of CH.

the simplest whole-number ratio of atoms in a compound. Different covalent compounds can have the same empirical formula if they have different molecular structures that still result in the same ratio of atoms.
Yes, covalent compounds can have the same empirical formula if they have different structural formulas. This means they have the same ratio of elements but differ in how the atoms are arranged in the molecule.
In this instance, the empirical formula is the same as the formula unit: NaNO3
An empirical formula refers to the chemical formula that indicates the simplest ratio of atoms in a compound. Two different compounds may have the same empirical formula.
molecular structures. The molecular formula of formaldehyde is CH2O, while acetic acid has the molecular formula CH3COOH. Despite having the same empirical formula, their arrangement of atoms is different, resulting in distinct chemical properties.
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.
