4. What is “Mole”?
Standard scientific Unit to count atoms and molecules
The mole designates an extremely large number of units,
6.022 × 1023
which is the number of atoms determined experimentally to be found in 12 grams of carbon-12
Carbon-12 was chosen arbitrarily to serve as the reference standard of the mole unit for the International System of Units (SI)
The number of units in a mole also bears the name Avogadro’s number, or Avogadro’s constant, in honor of the Italian physicist Amedeo Avogadro (1776–1856).
