Answer:
Avogadro's number is a proportion that relates molar mass on an atomic scale to physical mass on a human scale. Avogadro's number is defined as the number of elementary particles (molecules, atoms, compounds, etc.) per mole of a substance. It is equal to 6.022×1023 mol-1 and is expressed as the symbol NA.

Answer:
hey mate here is ur ans...
The mole is the unit of amount in chemistry. ... A mole of a substance is defined as: The mass of substance containing the same number of fundamental units as there are atoms in exactly 12.000 g of 12C. Fundamental units may be atoms, molecules, or formula units, depending on the substance concerned.
The Avogadro number, sometimes denoted N or N₀, is the number of constituent particles that are contained in one mole, the international unit of amount of substance: by definition, exactly 6.02214076×10²³, and it is dimensionless. It is named after the scientist Amedeo Avogadro.
What is the relation between an atomic number and a mass number? Atomic number is actually the number of protons in an atom while mass number is the number of nucleons i. e, number of protons plus the number of neutrons. Basically, Mass number = Atomic number + No. of neutrons.
