Question

Definition of mole.

Answer 1

Mole:

1. A mole is defined as the quantity of a material that includes precisely $6.02214076\mathrm{X}{10}^{23}$ of the substance's elementary entities. A substance's mass that has the same number of fundamental units as there are atoms in precisely 12.000 g of 12C is referred to as a mole.
2. Quantities that cannot be quantified using units like grams or milligrams are referred to as moles. A mole thus counts the number of atoms, ions, or molecules.
3. The following formula can be used to determine how many moles of material are present in a given pure sample:
   $\mathrm{n}=\frac{\mathrm{N}}{{\mathrm{N}}_{\mathrm{A}}}$, where n is the quantity (or elementary item) in moles, N is the total number of elementary entities in the sample,
4. ${\mathrm{N}}_{\mathrm{A}}$ is the Avogadro constant. The number $6.02214076\mathrm{X}{10}^{23}$ is popularly known as the Avogadro constant.

Therefore mole is the quantity of a material that includes precisely $6.02214076\mathrm{X}{10}^{23}$ of the substance's elementary entities.
