Hint: We already have heard the concentration of a substance given in terms of a mole. A mole is the unit of measurement for the amount of a substance. Here, we have to determine the symbol for the SI unit of mole. The SI unit is an international system of units.
Complete answer:
The concept of mole is widely used in chemistry as a convenient way to express the concentration or amount or reactant and product in a chemical reaction. The mole can be used to measure the amount of any entities i.e. it can be atoms, ions or molecules etc.
Earlier, the definition of mole is that one mole as the amount of a substance in grams of carbon- (an isotope of carbon)
Mole is also defined as the amount of a substance that contains exactly number of elementary entities. These entities can be ions, atoms or molecules of the given substances. The number is termed as Avogadro number. For example- one mole of water contains number of molecules.
The symbol for the SI unit of mole is mol.
Additional information-
Mole is used to represent the amount of a substance. For element or a compound, number of mole is determined by using this formula-
Number of moles (n) =
And its SI unit is mol.
Note:
The concept of mole is basically based on the count of particles. The particles that are counted are chemically identical entities. Also, the mass of one mole of a substance is equal to its relative atomic and molecular masses.
