Any molecular formula where the subscripts do not have a common factor that can divide them all.
For example: CH4 (methane) is a molecular formula that is also an empirical formula because there is no number (other then one) that can divide both the 4 and the 1.
Take ethane as another example. It hasn't the empirical formula which is similar to the molecular formula.
Molecular formulas that are also empirical formulas include compounds like water (H2O), methane (CH4), and hydrogen peroxide (H2O2). In these cases, the molecular formula is the same as the empirical formula because the compounds consist of only one type of atom.

What is the contrast between molecular formulas and empirical formulas?
Molecular formulas show the actual number of atoms of each element in a compound, while empirical formulas show the simplest whole number ratio of the atoms in a compound. Molecular formulas provide more specific information about the compound's composition compared to empirical formulas.
What is the difference between empirical and molecular formula?
An empirical formula is one that shows the lowest whole number ratio of the elements present. The molecular formula shows the composition of the molecules. An example is phosphorus pentoxide, P2O5 empirical formula, P4O10 molecular formula.
Which compound has the empirical formula ch2o?
CH2O is not only the empirical but also the molecular formula for formaldehye. It is also the empirical but not the molecular formula for hydroxyacetaldehyde, acetic acid, methyl formate, 1,3-dihydroxyacetone, and many other compounds.
What are the molecular formula and the empirical formula for benzene?
The molecular formula for benzene is C6H6, and the empirical formula is also C6H6. The empirical formula represents the simplest whole-number ratio of atoms in a compound, while the molecular formula gives the actual number of each type of atom in a molecule.
What is the empirical formula of diborane?
C2H4Br2 is the molecular formula for dibromoethane, it is also known as ethylene bromide.
What molecular formulas are an empirical formula?
Any molecular formula where the subscripts do not have a common factor that can divide them all. For example: CH4 (methane) is a molecular formula that is also an empirical formula because there is no number (other then one) that can divide both the 4 and the 1. Take ethane as another example.

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.

What is the empirical formula of diborane?
C2H4Br2 is the molecular formula for dibromoethane, it is also known as ethylene bromide.
How are molecular and empirical formulas related?
The empirical formula shows the simplest whole-number ratio of elements in a compound, while the molecular formula indicates the actual number of each type of atom present in a molecule. The molecular formula can be a multiple of the empirical formula if the compound contains a repeating unit.
What is the molecular formula of a compound with an empirical formula of CH?
The molecular formula of a compound with an empirical formula of CH is likely to be CH, as there is only one carbon atom and one hydrogen atom in the empirical formula. In this case, the empirical formula is also the molecular formula.
What could be a molecular formula for the empirical formula C2H2?
The molecular formula for the empirical formula C2H2 is also C2H2. The empirical formula gives the simplest whole number ratio of atoms present in a compound, whereas the molecular formula provides the actual number of atoms of each element in a molecule.
Is the formula for methane both a molecular and an empirical formula?
Yes, the formula for methane (CH4) is both a molecular formula and an empirical formula. The molecular formula shows the actual number of each atom in a molecule (4 hydrogen atoms and 1 carbon atom), while the empirical formula gives the simplest whole-number ratio of atoms in a compound (CH4).
What is the empirical formula for butane?
Well you know that Butanoic Acid's Molecular formula is C3H7COOH, and Empirical formula is a compound showig the simplest ratio of numbers of atoms of each element in the compound. Now the question is, can you simply C3H7COOH ? Nope! Then the Empirical formula is also C3H7COOH
