Answer 2

To understand the unit of one mole,

To understand the unit of one mole,first we need to understand" mole concept".

Mole Concept:

• It is not practically possible to find the mass of a minute particle like an atom,a molecule,or an ion,etc.
• Therefore ,a collection of 6.022*10^23 elementary particles called mole is taken for all practical purposes.

Mole is simply like a dozen or a gross .A dozen is a collection of 12 objects,a gross is a collection of 144 objects, similarly a mole is a collection of 6.022*10^23 particles (atoms or molecules or ions).

A mole is a amount of pure substance containing the same number of chemical units as there are atoms in exactly 12 grams of carbon -12.

Note:When the particle is not specifically mentioned ,then one mole is taken as 6.02*10^23 molecule.
