These two compounds has different molecular formulas.
Empirical formula is a useless notion; important is the molecular formula.
This is an empirical formula - a formula without indication about the structure of the molecule.
Empirical formula is the simplest formula that shows the simplest ratio of the different types of atoms in it. tartaric acid is made up of C4H6O6, which can be further simplified to be C2H3O3.
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.
C2H4O2 normally written as CH3COOH to show the presence of the carboxyic acid group

The formula for acetic acid is: CH3COOH
CH3COOH is the chemical formula for acetic acid.
I believe you are asking about the formula for ethanoic acid rather than ethonoic acid, which doesn't exist. Ethanoic acid is the proper, systematic (IUPAC) name for acetic acid. The molecular formula is: HOOC-CH2CH3.
Acetic acid has the formula of CH3COOH. It consists of carbon, hydrogen and oxygen as its constituent molecules.
Vinegar is highly diluted acetic acid. Acetic acid has the molecular formula of C2H4O2. The structural formula for acetic acid is CH3COOH
