Avogadro’s number
Avogadro's number is the number of "elementary entities" (usually atoms or molecules) in one mole. It is 6.0221415 × 1023
A mole of anything has the same number of molecules as a mole of anything else. The why comes from the fact that this is the standard definition as agreed by scientists. We have to have standards for things to work. A mole of anything contains an Avagadro number of particles. That number is 6.022 x 1023
One mole of any element contains Avogadro's number of atoms, which is approximately 6.022 x 10^23 atoms. Beryllium and magnesium are both in Group 2 of the periodic table, so they have the same number of atoms in one mole.
The number is 6,022140857.10e23.
The number of ions in a 6,58 mole sample of NaCl is 79,25137367812.10e23.
No number since mole is an animal.

A mole is equal to 6.022 x 1023. This number is called Avagadros number. A mole is generally abreiviated as "n".
Avogadro's number is the number of atoms or molecules of a substance that are present in one mole of that substance. It is relevant to the mole by its very definition!
A mole represents a set number of molecules, not just 1 molecule. There are avagadro's number of molecules in a mole. Avagadro's number: 6.022x10^23
It is the number of particles in a mole of any substance
Mole fraction is dimensionless. It's the amount of moles of species "A" divided by the total amount of moles in the mixture. So "mole A / mole total" equals "dimensionless". To add clarity in the use of mole fractions, one could add as "unit" mole A / mole "mixture".
The name given to the number of particles in a mole is Avagadro's number/constant
One mole of any element contains Avogadro's number of atoms, which is approximately 6.022 x 10^23 atoms. Beryllium and magnesium are both in Group 2 of the periodic table, so they have the same number of atoms in one mole.
The number is 6,022140857.10e23.
Both one mole of carbon and one mole of sodium contain Avogadro's number of atoms, which is approximately 6.02 x 10^23 atoms. This quantity is true for all elements or substances when considering one mole.
