Answer 2

Hii Mate here is your answer,

☆ What is a mole?

A Mole is a link between the mass of atoms or molecules and the number of atoms or molecules .

A connection between the numbers of atoms and the mass of it.

Mathematically :

1 mole of atoms = 6.022 × 10^23 atoms
1 mole of molecules = 6.022×10^23 molecules.

So,6.022× 10^23 is a constant which is 1 mole.
This refers the numbers of atoms or molecules.This is known as Avogadro Number.

》Link between Mole and Gram atomic mass

1 mole of atoms of an element has a mass equal to the gram atomic mass of the element .

e.g. 0xygen has gram atomic mass 16 that is 1 mole of it.
Similarly,
2o= 32 g = 2 moles of oxygen

This rule is also applicable for the molecules of different elements.

The gram atomic mass of a substance represents the mass of one mole of atoms of that substance.

So, we can write the below formula -----------

No. of atoms × A.N. = Moles
Moles× Gram Atomic Mass = Mass

No. of moles = Given Mass/ G.A. Mass
