**Hint:**Nitrogen (N) is a non-metallic element of Periodic Group 15 [Va]. It is a colourless, odourless, and tasteless gas that makes up the majority of the Earth's atmosphere that is found in all living things. In the International System of Units, the mole is the unit of measurement for the amount of substance.

**Complete answer:**

The mass of a material made up of an equal number of specific units is known as a mole. The atoms in 12 g, for example, are the same as 12C. Depending on the substance, the fundamental units may be ions, electrons, or formula units.

The number of chemical elements is expressed as a mole fraction. The magnitude of 6.023 x 10²³ is equivalent to one mole of any material (Avagadro number). It may be used to quantify the end products of a chemical reaction. Mol is the unit of measurement.

The formula for calculating the number of moles is as follows:

\[{\text{ Number of Moles }} = \frac{{{\text{ Mass of substance }}}}{{{\text{ Mass of one mole }}}}\]

Mass of substance given = 28 g

Mass of 1 mole of Nitrogen (N₂) = 14 g

\[{\text{ Number of Moles }} = \frac{{{\text{ 28 }}}}{{{\text{ 14 }}}}\]

Number of moles = 2

The mole is basically a particle count. The particles being counted are usually chemically similar structures that are uniquely distinct. A solution, for example, could have a certain amount of dissolved molecules that are more or less independent of one another. The constituent particles of a solid, on the other hand, are set and bound in a lattice structure, but they can be separated without losing their chemical identity. As a result, the solid is made up of a certain number of moles of these particles.

**Note:**

A substance's molar mass is the mass of one mole of the substance expressed in gramme multiples. The number of moles in the sample is the quantity of material. The magnitude of molar mass is numerically the same as the mean mass of one particle, calculated in daltons, for most practical purposes. Water, for example, has a molar mass of 18.015 g/mol. The use of the molar volume or the calculation of electric charge are two other approaches.
