Formula: Particles = Moles x 6.02214076e23
Worked example โ 2.5 moles = 1.5055e24 water molecules
Formula
Particles = Moles x 6.02214076e23
Multiply the number of moles by Avogadro number (6.02214076e23) to get the number of particles. For the reverse, divide the number of particles by Avogadro number to get moles. The particle type (atom, molecule, ion) must be specified.
Worked Examples
Example 1: Converting Moles of Water to Molecules
Problem:How many molecules are in 2.5 moles of water?
Solution:Particles = moles x Avogadro number Particles = 2.5 x 6.02214076e23 Particles = 1.505535e24 molecules
Result:2.5 moles = 1.5055e24 water molecules
Example 2: Converting Particles to Moles
Problem:A sample contains 3.01e23 atoms. How many moles is this?
Solution:Moles = particles / Avogadro number Moles = 3.01e23 / 6.02214076e23 Moles = 0.4998 mol
Result:3.01e23 atoms = 0.4998 moles
Frequently Asked Questions
What is Avogadro number and how is it used to convert moles to particles?
Avogadro number is exactly 6.02214076 times 10 to the 23rd, representing the number of constituent particles (atoms, molecules, ions, or other entities) in one mole of a substance. To convert moles to particles, simply multiply the number of moles by Avogadro number. For the reverse conversion, divide the number of particles by Avogadro number. This constant was redefined in 2019 by the International Bureau of Weights and Measures to be an exact value rather than a measured one.
What types of particles can moles represent?
A mole can represent any type of elementary entity: atoms (for elemental substances like iron or gold), molecules (for molecular compounds like water or glucose), ions (for ionic species in solution), formula units (for ionic compounds like NaCl), electrons (in electrochemistry), or photons (in photochemistry). It is essential to specify the type of particle when using moles, because one mole of water molecules contains 3 moles of atoms (2 hydrogen plus 1 oxygen). The IUPAC requires that the entity be specified when using the mole.
How large is Avogadro number in everyday terms?
Avogadro number is incomprehensibly large. If you counted one particle per second, it would take approximately 1.9 times 10 to the 16th years to count one mole of particles, which is over a million times the current age of the universe. One mole of standard playing cards stacked on top of each other would reach from the Earth to a point beyond the nearest star, Proxima Centauri, approximately 8.5 times 10 to the 17th meters. These comparisons illustrate why chemists need the mole concept to work with atomic-scale quantities.
Why was Avogadro number fixed to an exact value in 2019?
In 2019, the International System of Units (SI) was revised so that several fundamental constants, including Avogadro number, were fixed to exact defined values. Before this revision, Avogadro number was experimentally measured and had associated uncertainty. By defining it as exactly 6.02214076e23, the mole is now defined in terms of a fixed number of particles rather than being tied to the mass of carbon-12. This change improved measurement consistency worldwide and decoupled the mole from the kilogram definition.
