Final answer:
The mole is a unit used to measure the amount of substance, consisting of exactly 6.02214076 × 10²23 particles, which is Avogadro's number.
Step-by-step explanation:
When a sample is described using the units mole, what is being measured is the amount of substance it contains. The mole (mol) is a unit of measurement in the International System of Units (SI) for amount of substance. It is similar to familiar counting units like pair, dozen, and gross but used for a very large number of microscopic entities such as atoms, molecules, and ions.
A mole is defined as containing exactly 6.02214076 × 10²23 of these entities, which is also known as Avogadro’s number. This large number provides a bridge between the easily measured macroscopic bulk mass and the number of atoms, an essential fundamental property in chemistry.
The mole is a unit used in chemistry to measure the amount of a substance. It provides a specific measure of the number of atoms or molecules in a sample of matter. For example, one mole of a substance is equal to 6.02214076 × 10^23 atoms or molecules of that substance. The mole allows chemists to easily relate macroscopic properties, such as mass, to the number of particles in a sample.
