Question

What is the relationship between the mole and Avogadro’s number?

Answer 1

Hint: The moles, we can calculate in so many ways. One of the ways is if we want to calculate the moles of an atom means the first atomic weight of that atom. The atomic weight of the atom depends on the number of protons and neutrons in the atom. One of the ways is if we want to calculate the moles of molecules means the first atomic weight of all the atoms in the molecules. Another way of calculating the moles of the atom depends on the number of that atom and Avogadro’s number. Another way of calculating the moles of molecules depends on the number of those molecules and Avogadro’s number.

Complete answer:
The number of atoms of the element is equal to the number of moles of the atom multiplied by Avogadro’s number. The numerical value of Avogadro’s number is $$6.022\times {10}^{23}$$. The symbol of Avogadro’s number is NA.
$$\text{The Number Of Atoms = number of moles}\times 6.022\times 1{\text{0}}^{\text{23}}$$
From the above formula, we can make the relationship between the mole and Avogadro’s number.
$$\text{The Number Of Moles = }{\displaystyle \frac{\text{The Number Of Atoms}}{\text{6}.022\times 1{\text{0}}^{\text{23}}}}$$
The main thing is one atom is equal to $$6.022\times {10}^{23}$$number of atoms.
According to the above discussion, we now know the relationship between the mole and Avogadro’s number.

Note:
The mole is one of the important units in chemistry. All the chemical reactions are expressed in terms of the moles of the reactant and product. If one reaction is completed or not is also determined by the moles of the reactant and product.
Moles are defined as the given mass of the atom is divided by the atomic weight of the atom.
$$\text{Moles = }{\displaystyle \frac{\text{given weight of the atom}}{\text{atomic weight of the atom}}}$$
$$\text{Given Weight Of The Atom = number of moles}\times \text{atomic weight of the atom}$$
If we want the given weight of the atom to be the product of the number of moles of the atom and the atomic weight of the atom.
