What is molecular formula?
Molecular formula is the chemical formula, which represents the actual numbers of atoms of each element present in a compound.
The mass of an atom of an element is called its atomic mass. The unit of atomic mass is any form of a mass like milligram, gram.Molar of a solution is defined as the quantity of gram-moles of solute softened in 1 liter of a solution. Molecular is as the grouping of atoms. A molecular is a combination of atom. Under the normal condition the elements are present in free state of an atom. The molecular mass of a matter is the calculation of the atomic masses of all atoms in a molecule of the substance.
A molecular shows all the physical and chemical properties of that matter. Molecules can obtain by same or different combination of elements.
Molecule formula is related to empirical formula.
Molecule formula = n * empirical formula
Where n= (molecular mass / empirical formula mass)
Example for molecules: C2H6:
The molecule benzene consists of two carbon atoms and six hydrogen atoms. Here the molecule benzene is the combination of carbon and hydrogen elements.
The molecular formula does not provide information on which atoms are arranged in a molecule. The structural formula is needed to determine the actual arrangement of the atoms in a molecule. Methyl alcohol, for example, consists of a carbon atom that has three hydrogen atoms and one oxygen atom bonded to it. The oxygen atom is, in turn, bonded to a fourth hydrogen atom. The molecular formula is CH4O does not convey this specificity of arrangement as does the structural formula, CH3OH.
Like the molecular formula, the structural formula of a substance gives the exact number of atoms of each element per molecule. In addition, however the structural formula depicts how the atoms are bonded to each other. As a result, the structural formula is essential for the determination of molecular shape and the properties associated with particular molecular geometric arrangements.
