Firstly divide percentages by molar mass of that element
C
65.45/12.01=5.45
H
5.45/1.01=5.40
O
29.09/16=1.82
Then divide the result of the first step by the smallest answer
C
5.45/1.82=3
H
5.40/1.82=3
O
1.82/1.82=1
Empirical Formula is C3H3O
If the molar mass is 110.1 we can divide this by our empirical formulas molar mass to get the molecular formula.
so 110.1/(12.01x3+1.01x3+16)=110.1/55.06=2
so the molecular formula is C6H6O2
C6H12O3 is a molecular formula that contains 54.5% C, 9.1% H, and 36.4% O and has molar mass of 132 amu.
With a molecular formula we can calculate the molar mass and the chemical composition of a compound, also we can write chemical equations.
The molecular formula represents the actual number of each type of atom in a molecule, providing the specific composition of the compound. In contrast, the empirical formula gives the simplest whole-number ratio of the atoms in the compound, which may not reflect the actual quantities. For example, the molecular formula of glucose is C6H12O6, while its empirical formula is CH2O. Thus, the molecular formula can contain multiple empirical formulas, depending on the complexity of the molecule.
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.
The molecular formula of a compound can not be determined solely based on its molar mass. In this case, without additional information, it is not possible to determine the molecular formula of the compound CH2.
The formula of the compound and the Atomic Mass of its elements.
C6H12O3 is a molecular formula that contains 54.5% C, 9.1% H, and 36.4% O and has molar mass of 132 amu.
A compound formula, or molecular formula, tells you about the chemical composition of the substance in terms of the number of atoms of that element that are present. From there, the empirical formula may also be derived by simplifying the molecular formula, as well as its structural formula.
The molecular formula of the compound can be calculated from the composition of element in a compound. The next steps are involved in the calculation of percentage of every element in a compound.
With a molecular formula we can calculate the molar mass and the chemical composition of a compound, also we can write chemical equations.
Percent composition can be used to calculate the percentage of an element/compound in a mixture. From the percent composition, you can also find the empirical formula. And from the empirical formula you can find the actual molecular weight.
draw a structural formula for organics, write a chemical formula (molecular formula or ionic formula) for simpler compounds.

The molecular formula of the compound with the keyword C8H14O3 is C8H14O3.
You should solve for an empirical formula when you are given the percent composition of elements in a compound or when you have the molar mass of the compound but not the molecular formula. The empirical formula provides the simplest whole-number ratio of atoms in a compound.
The molecular formula of a compound is based on the types and numbers of atoms present in a molecule. It provides the actual number of atoms of each element in a compound, giving the ratio of different elements in the molecule.
This is the chemical formula (empirical formula) or the formula unit of this compound.
