The molecular formula deals with showing the actual number of atoms in a molecule whereas the empirical formula expresses the smallest possible whole number in a molecule. Molecular Formula can be calculated easily based on the empirical formula when the molar mass value is known.
A molecular formula contains the symbol of chemicals and expresses the number of atoms of each element present in the molecule. The proportion of various chemicals can be known from the chemical formula. It is a way of showing simple chemical structures rather than full chemical molecular formulas.
An empirical formula relates to the simplest formula for an element. It expresses the ratio of subscripts of the smallest possible whole number of the elements present in the chemical formula. The smallest integer subscript of a substance can be shown by an empirical formula. It gives the information about the ratio of atom numbers in the chemical compound.
What is the Molecular formula definition?
It gives the proper idea about the presence of every element present within the molecular compound. It shows the whole-integer ratio of atoms in a compound which is an equivalent to or a multiple of the compound’s formula.
The atomic arrangement and bonding can not be known to see the molecular formula. The symbols of elements and numbers are used to represent this formula. It also uses various symbols like parentheses, dashes, brackets, and plus (+) and minus (–) signs.
Molecular Formula Examples
For example, in NH3, the subscript under Hydrogen shows that there are three atoms of hydrogen present, whereas the lack of subscript under Nitrogen shows it has only one atom of Nitrogen present.
The molecular formula of sugar is C12H22O11
What is an Empirical Formula?
It is defined as the simplest whole-number ratio of atoms in a molecule of compound. The atomic percent composition in a compound can be known from this formula.
This formula expresses the smallest possible whole number of the elements present in a compound and provides information about the ratio of the number of atoms present in the compounds.
The relationship between this formula with the molecular formula is given by,
Empirical Formula = Molecular Formula/n
Empirical Formula Examples
For example, C6H6 is the molecular formula of Benzene which can be represented by 6(CH)
So, the empirical formula of glucose molecule is CH.
The molecular formula of Acetylene is C2H2 which can be represented as 2(CH)
So, the empirical formula of Acetylene is CH.
Molecular Formula Vs Empirical Formula
Molecular formula shows the possible number of atoms present in a molecule, whereas the simplest form of the composition of a compound is expressed by the empirical formula.
The actual molecular weight of a compound can be known by the chemical formula, whereas the empirical formula expresses the mass percentages of elements in a compound.
The molecular formula is used to draw the various chemical reactions, whereas the empirical formula is used to express the percentage composition of a molecule.
The molecular formula of glucose is C6H12O11, whereas the empirical formula of glucose is CH2O.
The molecular formula of Urea is NH2CONH2, whereas the empirical formula of Urea is CH4N2O.
The molecular formula of Magnesium oxide is MgO, whereas the empirical formula of magnesium oxide is MgO.
How to find an empirical formula?
There are some steps involved in calculating the empirical formula which are given below:
The first step relates to the percentage calculation of elements in the compound. It can be done by experimental data or by converting mass data to percentages.
The second step involves the percentage conversion of the components into grams.
The third step associates the conversion of the atomic mass of each element into grams to moles by using their respective atomic masses.
The fourth step relates the determination of the mole ratio by dividing each element’s mole by the smallest number of moles among them.
The fifth step is associated to turn the calculated mole ratio to the nearest whole number. If the ratio is closer to a whole number but not exact, it can multiply all ratios by an appropriate integer for getting the whole numbers.
The last step involves writing an empirical formula by using the whole-number mole ratios for the corresponding elements.
Empirical formula calculation examples
Problem 1: A compound consists of oxygen and hydrogen whose percentages are 88.79% and 11.19% respectively. Find out the empirical formula of this compound.
Solution: The mass percentage of each atom in this compound matches the grams of each element if it assumes that 100.0g of substance present in the experimental place. So, it can be written that the following:
H=11.19g and O=88.79g
Now, it must be converted the grams of each element into moles and can be calculated by following
H= (11.19/1.008) = 11.10 mol H atoms because the molar mass of H=1.008g/mol
O= (88.79/16.00) = 5.549 mol O atoms because the molar mass of O= 16.00g/mol
Now, it must be divided into the lowest number altered the numbers to whole numbers by following
H =11.10/ 5.549= 2.000 and O = 5.549/ 5.549= 1.000
So, the simplest ratio of hydrogen to oxygen is 2:1 and the empirical formula is H2O.
Problem 2: There is a compound formed by the combination of 1.926g of sulfur(S) with 2.233g of iron (Fe). Find out the empirical formula of this compound.
Solution: The first step involves the conversion of grams of each element to moles by the following:
Fe= (2.233g /55.85g) = 0.03998 mol Fe atoms because the molar mass of Fe=1.008g/mol
S= (1.926 /32.07) = 0.06006 mol S atoms because the molar mass of S =32.07g/mol
The second step involves the dividing calculated number by the smallest number and changing the numbers to whole numbers by the following:
Fe =0.03998/0.03998 = 1.000 and S = 0.06006/0.03998mol = 1.502
Now, it is seen that the calculated number of Sulphur mole is a fractional ratio that can be turned into a whole number by multiplying a number.
Fe= (1.000) * 2 = 2.000 and S= (1.502) * 2 = 3.004
So, the empirical formula of this compound is Fe2S3.
What is molecular weight?
It is defined as how many grams of atoms there are in one mole of a chemical substance. It expresses how much of a substance is present. It is the sum of the atomic weights of the atoms in a molecule that are bound together by some kind of mutual interaction. For example, the molecular weight of CO2 is calculated as (1×12) + (2×16) = 44, where 12 and 16 are the atomic weights of Carbon (C) and Oxygen (O) atoms respectively. It is possible to determine the molecular weight of a compound by either chemical methods or mass spectrometry.

Frequently Asked Questions (FAQs)
What is a molecular formula with an example?
It expresses the total number of individual atoms in a compound’s molecule. We get information about the presence of a number of each type of atom in a molecule in a substance. It has a close linkage with the gram molecular masses. For example, the molecular formula of Mohr salt is (NH₄)₂Fe(SO₄)₂·6H₂O and the chemical formula of soap is C17H35COO– plus a metal cation, either Na+ or K+
What is an empirical formula with an example?
It indicates the simplest whole-number ratio of atoms present in a compound. For example, the empirical formula of Hydrogen peroxide is HO, whereas the chemical formula of Hydrogen peroxide is H2O2.
What is the structural formula?
It is the actual representation of the molecular structure to show the proper atomic arrangement in real three-dimensional space.
