Yogita Ingle 5 years, 10 months ago

Atoms and molecules are too small to count. To solve this problem their numbers are expressed in terms of Avogadro’s number (N_A = 6.023 10²³). Mole is the number equal to Avogadro’s number just like a dozen is equal to 12, a century means 100, a score means = 20.

Mole can be defined as a unit which represents 6.023 x10²³ particles of same matter.
