Hi
Atoms and molecules are very small in size but their numbers in even a small amount of any substance is very large. To handle these large numbers a unit of similar magnitude is required. Just as we denote dozen for 12 items and score for 20 items, we use molefor microscopic entities. 1 mole can be defined as “the amount of substance that contains as many specified elementary particles as the number of atoms in 12 grams of carbon-12 isotope.”
Now, mass of a carbon-12 atom = 1.99 × 10-23 g
Number of atoms in 1 mole
=12g/ mol of ^12C atom

1.99*10-23g/^12 C atom
Hence, 1 mole = 6.022 × 1023 atoms
Best wishes!
