Explanation:

The Mole::

The identity of a substance is defined not only by the types of atoms or ions it contains, but by the quantity of each type of atom or ion. For example, water, H2O, and hydrogen peroxide, H2O2, are alike in that their respective molecules are composed of hydrogen and oxygen atoms. However, because a hydrogen peroxide molecule contains two oxygen atoms, as opposed to the water molecule, which has only one, the two substances exhibit very different properties. Today, we possess sophisticated instruments that allow the direct measurement of these defining microscopic traits; however, the same traits were originally derived from the measurement of macroscopic properties (the masses and volumes of bulk quantities of matter) using relatively simple tools (balances and volumetric glassware). This experimental approach required the introduction of a new unit for amount of substances, the mole, which remains indispensable in modern chemical science.

Avogadro's no:

The Avogadro constant is the proportionality factor that relates the number of constituent particles in a sample with the amount of substance in that sample. Its SI unit is the reciprocal mole, and it is defined as NA = 6.02214076×10²³ mol⁻¹. It is named after the Italian scientist Amedeo Avogadro.

Answer:

mole means A mole s that quantity of a substance whose mass in grams is equal in magnitude to the molecular mass of that substance in Dalton's

Avogadro's numbers means the number of molecules in one mole of any substance is constant the Italian scientist Avogadro dud pioneering work in this context . Therefore this number is called Avogadro's numbers and is denoted by the symbol Na
