Yes - it is Avagadro's number/constant
A mole.
The name given to the number of particles in a mole is Avagadro's number/constant
*Avogadro's Constant is 6 x 10^23, representing the number of particles (ie. atoms/ions/molecules) in one mole of any substance :)
Number of particles = number of mol x avogadro constant = 1 x 6.02 x 1023
A mole of particles is a very large number, equivalent to 6.022 x 10^23 particles. This number is known as Avogadro's number and represents a mole of any substance, whether atoms, molecules, ions, or other particles.
One mole of NaCl = 6,02214129(27) × 1023 mol−1 (molecules ) - this is number (constant) of Avogadro.
Avogadro constant or number is the number of atoms in one mole, which is equal to 6.0221415 × 10^23. Edited to: The Avogadro constant is the number of particles (atoms, molecules or compounds) in one mole of a substance. It is the number of atoms in exactly 12g of carbon-12. As for all other elements, one mole of those is found in the relative atomic mass of that substance which is calculated relative to one twelfth of a carbon-12 atom e.g. one mole of oxygen atoms is in 16g of oxygen... and a mole was experiemtally worked out to contain 6.0221415 × 10^23 particles.
The answer is Avogadro's constant, 6.022 141 29×1023
Avogadro's number is a constant (6.022 x 10^23) that represents the number of particles (atoms, molecules, ions, etc.) in one mole of a substance. It is used to convert between the mass of a substance and the number of particles it contains.
A mole.
It is the number of particles in a mole of any substance
One crazy fact about Avogadro's number is that it is so large that if you were to count one mole of particles at a rate of one per second, it would take you over 19 million years to finish counting them all.
