Knowing the etymological origin of the word that we are going to analyze in depth below is vital to be able to understand and establish its meaning. Specifically, we can state that it is found in Latin and more exactly in the word moles which can be translated as “mass”.

It is known by the name of mole to one of the fundamental physical quantities contemplated by the International System of Units. This Unit It is used to measure the amount of all kinds of substances present in a certain system.


The mole is a fundamental physical quantity.

Analyzing the concept

The mole, experts say, reflects the amount of substance that has a specific number of elemental entities such as atoms can be found in twelve grams of carbon-12. This means that the number of elementary units (as in the case of atoms, molecules or ions, for example) that are reflected in a mole of substance is a constant that is not directly related to the type of particle or material in question. This amount is known as Avogadro’s number.

This constant, named after the scientist of Italian origin Amedeo Avogadro (17761856), allows to count microscopic particles from macroscopic measurements (as is the case of the mass).

This character, Count of Quaregna y Cerreto, who also worked as a professor at the University of Turin in the area of ​​Physics and who with this Avogrado law managed to make an important contribution to science. Basically with the same what he established was that identical volumes of gases that are in the same conditions, with regard to temperature and pressure, will have the same number of particles.

Mol and Avogadro’s number

Avogadro’s number, therefore, helps Chemistry experts express the weight of atoms. The equation states that one mole is equal to 6.022 x 10 to the 23rd power. It is an immense figure capable of reflecting a huge number of particles.

When expressing the total number of atoms that are identified in twelve grams of carbon-12, the mass in grams of one mole of atoms of an element always coincides with the atomic weight in atomic mass units of the same element. This means that Avogadro’s number allows conversions between the gram and the atomic mass unit.


The mole is linked to Avogadro’s number.

A municipality of Antwerp

MolFinally, it is a municipality located in the province of Antwerp (Belgium) and the acronym for Mac on Linux (a kind of software).

A town that has become one of the most popular tourist enclaves by travelers arriving in Belgium. And it is that in it, which has a population of around 30,000 inhabitants, the traveler is given the opportunity to enjoy their stay by practicing a wide number of water sports in the various lakes it has.

In the same way, it should not be overlooked that tourists also have the possibility of enriching themselves culturally by visiting the famous Abbey of Postel. In the 12th century is where the origin of this religious construction that belongs to the Romanesque style is found, although with the passing of time, and the different works that were carried out in it, elements of the Gothic and Baroque were included.
