Question

What is Avogadro’s number, and why is it useful

Answer 1

Avogadro's number is 6.022×1023 molecules. Scientists use it to discuss and compare large numbers. It is useful because substances in everyday quantities contain large numbers of atoms and molecules.

Answer 2

Avogadro’s number is 6.023 x 10^²³. It is the number of particles in 1 mole of substance. The particles can be atoms, molecules, ions and formula units.In everyday terms it is much easier to say 1 dozen of apples instead of 12 apples. Similarly scientists use Avogadro’s number to express large numbers as that makes the calculation simpler.
