MOLE How many moles are there for a mole of moles? Anura Hewagama

Objectives/Standards C4.6x Moles The mole is the standard unit for counting atomic and molecular particles in terms of common mass units. C4.6a Calculate the number of moles of any compound or element given the mass of the substance. C4.6b Calculate the number of particles of any compound or element given the mass of the substance.

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).
