The emperial formula of the given compound is C2H2O. the molecular formula of the given compound is C4H4O2.

Molecular formula: What is it?

The molecular formula, which is generated from molecules, reflects the total number of individual atoms that make up a compound's molecule.

The actual number of each type of atom in a compound's molecule is reported by a subscript in a molecular formula.

Gram molecular masses that are straightforward whole number multiples of the relevant empirical formula mass are assigned to molecular formulas.

Empirical formula: what is it?

The empirical formula, which is defined as the ratio of subscripts of the least whole number of the elements present in the formula, is the simplest formula for a compound.

The simplest formula is another name for it.

The formula of a compound serves as an empirical formula.

It gives the information about what proportion or ratio of numbers of atoms in the compound.

The percent composition of a compound directly leads to it's empirical formula.

Molecular Formula = n × Empirical Formula

n= molecular formula/ empirical formula

Thus here molecular formula is C4H4O2. so the lowest subscript integer is 2 thus n is equal to 2 . thus the empirical formula is C2H2O.
