Formula Molecular


Let us learn about Formula Molecular

Molecular Formula of a compound shows how many atoms of each element are present in a molecule of the compound.


An expression which states the number and type of atoms present in a molecule of a substance.


A formula in which only the elements and number of atoms of each element are shown, e.g. C5H12


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)
