What is MOL definition/concept/elaboration

In the field of chemistry, the mol is used as a measurement unit , more specifically it is a unit of mass. This unit allows referring to the number of atoms of a substance. The mol concept can be applied to both atoms and molecules.

The mol as a unit is used in chemistry or chemical engineering. Other related concepts are: molecular mass, atomic mass, mol-gram and Avogadro’s number.

To understand chemical reactions it is necessary to know the elementary particles of matter. The base particles are the atoms, which differ from each other. However, these differences are imperceptible as the atoms are very small. MOL

To facilitate this task, we can start with the following argument: that each class of atom has a different mass. With this criterion it is possible to distinguish the atoms by comparing their masses. To obtain this information it is necessary to establish a system of proportions between the different types of atoms. In other words, it is important to establish the relative mass of atoms in proportions. For this, in the 19th century, the Italian chemist Amedeo Avogadro created a system that is still in force today and is known as Avogadro’s number or constant.

The Avogadro number allows you to define the number of atoms of a substance

Atomic units are difficult to calculate. Because of this, Avogadro devised a constant that defines the number of atoms in a substance. Thus, Avogadro’s number indicates that 1 mole is equal to 6.022045 x 10 to 23 particles. This number allows you to encompass the set of atoms of a substance in a single block. Thus, in the language of chemistry, we can speak of one mole of oxygen combined with one mole of carbon, both of which result in one mole of CO. In this sense, Avogadro’s constant makes it possible to drastically reduce calculations of chemical compounds.

What is molar mass or atomic mass?

Atomic mass is the number of protons plus the number of neutrons. This means that atomic mass equals the actual physical mass of an atom.

If the atomic mass of carbon is 12 it means that one mole of carbon atoms weighs 12 grams. In this way it is possible to calculate the weight of an atom or the average mole weight. Molar mass is usually expressed in grams/mol. In other words, how much does 1 mole of an atom weigh? MOL
