Whyyy
Step-by-step explanation:
The mole should be considered a base unit in the SI system because it is widely used in chemical calculations as a standard unit for counting the number of particles in a substance. The mole allows for easy and accurate calculation of the amount of substance, which is a crucial aspect in many chemical processes. In addition, the mole is defined as the number of entities in a substance, such as atoms, molecules, or ions, and its definition is based on Avogadro's constant. The mole also has practical applications in fields such as pharmacology and environmental science, where the measurement of a specific quantity of a substance is essential.
In conclusion, the mole is a necessary unit for the SI system of units due to its widespread use in chemical calculations and its important role in accurately measuring the amount of substance in a variety of scientific disciplines.
