what is this constant?
It is the proportionality factor that relates the number of constituent particles in a sample with the amount of substance in that sample.
Avogadro constant
The Avogadro constant ("N" or "L") is the proportionality factor that relates the number of constituent particles (usually molecules, atoms or ions) in a sample with the amount of substance in that sample. Its SI unit is the reciprocal mole, and it is defined as It is named after the Italian scientist Amedeo Avogadro.

Avogadro constant [SEP] Introduction
The Avogadro constant ("N" or "L") is the proportionality factor that relates the number of constituent particles (usually molecules, atoms or ions) in a sample with the amount of substance in that sample. Its SI unit is the reciprocal mole, and it is defined as It is named after the Italian scientist Amedeo Avogadro. The numeric value of the Avogadro constant expressed in reciprocal mole, a dimensionless number, is called the Avogadro number, sometimes denoted "N" or "N", which is thus the number of particles that are contained in one mole, exactly . The value of the Avogadro constant was chosen so that the mass of one mole of a chemical compound, in grams, is numerically equal (for all practical purposes) to the average mass of one molecule of the compound, in daltons (universal atomic mass units); one dalton being of the mass of one carbon-12 atom, which is approximately the mass of one nucleon (proton or neutron).
