An empirical formula give information about the chemical composition of a compound.
Example: tetracycline with the empirical formula C22H24N2O8 has the following composition:
- carbon 59,44 %
- oxygen 28,81 %
- nitrogen 6,30 %
- hydrogen 5,45 %
If you're with plato the answer is ratios
Empirical formulas represent the simplest component of a molecule.
No: The formula NO shows equal numbers of nitrogen and oxygen atoms in the compound, but the formula NO2 shows twice as many oxygen atoms as nitrogen atoms.
C2H5O. Empirical formula is the simplest integer ratio of atoms.
The empirical formula of a compound shows the lowest whole number ratio of the elements in that compound; AKA simplest formula. The molecular formula describes the number of atoms of each element that make up the molecule or formula unit; AKA actual formula
Emperical formula give the smallest whole number ratio of atoms in a compound
Empirical formulas represent the simplest component of a molecule.
Ratios
the empirical formula and the molar mass
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.
No: The formula NO shows equal numbers of nitrogen and oxygen atoms in the compound, but the formula NO2 shows twice as many oxygen atoms as nitrogen atoms.
C2H5O. Empirical formula is the simplest integer ratio of atoms.
the empirical formula of a compound tells you the proportions of the elements in the compound. with that information you can make some inferences about the identity of the compound. for example a compound with an empirical formula CH4 tells us that for every carbon atom there are four hydrogen atoms. this means that the compound is methane because no other hydrocarbon can have these roportions (try drawing the lewis structure for C2H8, which doesnt exist. you cant!)

Emperical formula give the smallest whole number ratio of atoms in a compound
The molecular formula of this compound is N2H2. This is obvious because the empirical formula of a compound is the lowest positive integer ratio of atoms present.
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.
The formula unit for an ionic compound is similar to an empirical formula in that both give the simplest whole-number ratio of atoms of each element in a compound.
