Completion requirements
Conclusion
The mole provides a convenient way to convert between the number of atoms and the mass of a substance.

The mole is a method of counting; one mole is equal to 6.02 × 1023 particles. Such a large number of particles of a substance is required because atoms and molecules are so small.
The molar mass of a substance is a way of converting between moles and mass. By knowing the mass of a sample, molar mass can be easily measured using a laboratory scale.
You also looked at the law of conservation of mass, which states that during a chemical reaction, matter is not created or destroyed but is converted from one form to another.
