It is possible for different covalent compounds to have the same empirical formula because empirical formulas represent?
Empirical formulas represent the simplest component of a molecule.
What is Na2S2O4 formula is empirical formulas?
NaSO2
What is the empirical formula for Hg2F2?
Molecular formula is Hg2F2 . The empirical formula is HgF . For empirical formulas you reduce the numbers as far as possible.
How do you calculate Molecular formula from empirical formulaWhat could you do with that information to determine that the empirical and molecular formulas are related to one another by a factor of 6?
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.
What is the empirical formula for nitrogen dioxide?
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.
What do empirical formulas determine?
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.

How are the empirical and molecular formulas for a compuond related?
An empirical formula is a brutto formula; a molecular formula explain the structure of a molecule.

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.
Explain why the percent composition of certain compounds are not sufficient to determine the compounds molecular formulas?
Because unlike the empirical formula, the molecular formula does not have to be the simplest ratio.If by chance you are given the percent composition of the elements in a substance, you could calculate the empirical formula and then the empirical formula's mass. However, the molecular formula equation is molecular formula= (empirical formula)n, where n is the mass of the molecular formula divided by the mass of the empirical formula. You would, therefore, need to know the mass belonging to the molecular formula, which you are not given.
How are empirical and molecular formulas for a compound created?
An empirical formula is elaborated after the chemical analysis of a compound; for a structural formula more in depth studies are necessary.
Is definitely not an empirical formula C12H16O3 C6H12O4 C12H22O11 C3H8O2?
All are molecular formulas.
How is molecular formula C3H6 and molecular formula C6H12 related?
Both formulas are possible molecular formulas for the same empirical formula, CH2.
A compound found to contain 75.7 arsenic and 24.3 oxygen would have which of the empirical formulas?
As2O3
