What does the mole represent?

What is a mole and what does it represent?

A mole represents two things: 1. It represents a definite amount of the substance i.e. an amount of substance equal to its gram atomic mass or gram molecular mass. 2. It represents a definite number (6.022 × 1023) of atoms, molecules or ions of a substance.

What is the significance of the mole in our life?

The mole is important because it allows chemists to work with the subatomic world with macro world units and amounts. Atoms, molecules and formula units are very small and very difficult to work with usually. However, the mole allows a chemist to work with amounts large enough to use.
