The Empirical formula of Al2Br6 is AlBr3.
Molecular formula tells you how the actual number of atoms of each element are in one molecule of a compound. The empirical formula shows this same information as a reduced ratio.
For example:
H2O2 is the molecular formula of hydrogen peroxide. In one molecule of hydrogen peroxide there are two atoms of hydrogen and two atoms of oxygen.
This can be thought of as a 2:2 ratio of H:O. Reduced this ratio yields 1:1, and so the empirical formula is HO.
empirical formula shows the simplest ratio between atoms present in molecule.
For example, the empirical formula of glucose is CH2o [c6h12o6]. it shows simple ratio between carbon, hydrogen and oxygen.
molecular formula shows the actual number of combining atom in a compound. for example molecular formula of benzene is c6h6
Molecular formula is the actual representation of the constitution of the substance
while Empirical formula is the simplest representation of the molecular formula.
Molecular formula= Empirical formula*n
(where n= Molecular weight/Empirical formula weight)
Example :-
Ethene
Molecular formula =C2H4
Empirical formula=CH2
here CH2 is the simplest representation of molecular formula of Ethene.
Example of Empirical formula is : CO2
Example of Molecular formula is : C4O8
its more complex
Molecular formula is Hg2F2 . The empirical formula is HgF . For empirical formulas you reduce the numbers as far as possible.
In order to find molecular formula from empirical formula, one needs to know the molar mass of the molecular formula. Then you simply divide the molar mass of the molecular formula by the molar mass of the empirical formula to find out how many empirical formulae are in the molecular formula. Then you multiply the subscripts in the empirical formula by that number.
Molecular. The empirical formula would simply be S.
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.
Imperical fomula is similar to molecular fomula.It is in simpleset form
An empirical formula is a brutto formula; a molecular formula explain the structure of a molecule.
Both formulas are possible molecular formulas for the same empirical formula, CH2.
Molecular formula is Hg2F2 . The empirical formula is HgF . For empirical formulas you reduce the numbers as far as possible.
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.

Molecular formulas are used the most often, but empirical formulas do help at times. Often it's just to simplify the molecular formula, but this simplification can often tell you if it's in the same chemical family as other compounds and such.

All are molecular formulas.
Molecular. The empirical formula would simply be S.
An empirical formula is elaborated after the chemical analysis of a compound; for a structural formula more in depth studies are necessary.
