Question

Can any one explain mole concept.
Full explanation..... please. ​

Answer 1

Answer:

The mole is the unit of amount in chemistry. It provides a bridge between the atom and the macroscopic amounts of material that we work with in the laboratory. It allows the chemist to weigh out amounts of two substances, say iron and sulfur, such that equal numbers of atoms of iron and sulfur are obtained. 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. At present, our best estimate of the number of atoms in 12.000 g of 12C is 6.022 x 1023, a huge number of atoms. This is obviously a very important quantity. For historical reasons, it is called Avogadro's Number, and is given the symbol NA.

if it helps u then follow pls

Answer 2

Explanation:

A mole (symbol mol) is defined as the amount of substance that contains as many atoms, molecules, ions, electrons or any other elementary entities as there are carbon atoms in exactly 12 gm of . The number of atoms in 12 gm of is called Avogadro's number ..............here is your answer...mark as brainlist dear
