Assuming you came upon the empirical formula by chemical analysis, the molecular formula would be a multiple of (NO2)n. The vale for n (1, 2, 3 etc) would need to be established by investigation. In this case the molecular formula is N2O4. This molecule is in equilbrium with the monomer NO2. N2O4 is the more common species at low temperatures and is the form found in the solid. NO2 is paramagnetic as it has one unpaired electron.
we did this in our class today but i don't remember how to do it :P
those numbers suppose to be subscripts..
N2O5 already is an empirical formula, because there is no single integer by which both of its subscript numbers can be divided to produce an integer quotient.
The empirical formual for N2O4 is NO2
the answer should be NO3
It is still N2O5.

The formula for dinitrogen heptoxide is N2O7
Molecular formula is Hg2F2 . The empirical formula is HgF . For empirical formulas you reduce the numbers as far as possible.
NaSO2
The empirical formula for nitrogen dioxide is the same as its molecular formula - NO2. See related question below for more details on how to find empirical formulas.
Empirical formulas represent the simplest component of a molecule.

An empirical formula is a brutto formula; a molecular formula explain the structure of a molecule.
You think probable to dinitrogen pentoxide - N2O5.
The empirical formula for nitrogen dioxide is the same as its molecular formula - NO2. See related question below for more details on how to find empirical formulas.
Empirical formulas represent the simplest component of a molecule.
Both formulas are possible molecular formulas for the same empirical formula, CH2.
Empirical formulas determine the ratio of atoms of different elements within a chemical compound and can be derived by dividing the number of each element's atoms by their greatest common factor. They do not necessarily describe the full chemical makeup of a molecule. For example, benzene has the formula C6H6 but its empirical formula is simply CH because there is one hydrogen atom for every carbon atom. Glucose has the molecular formula of C6H12O6; its empirical formula is CH2O. Because the molecular formula for water, H2O, cannot be further simplified (empirical formulas have only whole numbers) H20 is also its empirical formula.
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.
