Question

What is the value of Avogadro’s number?

Answer 1

Hint: As we know, Avogadro’s number or Avogadro’s constant is the number of units in one mole of any substance or compound. These units can be either ions, electrons, protons, atoms or molecules which are based on the character of the reaction and the product type. So here we have to tell its value.

Complete answer:
Let us discuss about Avogadro’s number as follows:-
-Avogadro’s number: It is generally the number of units in one mole of any substance or compound and these units can be either ions, electrons, protons, atoms or molecules that are based on the character of the reaction and the product type.
-The value of Avogadro’s number is fixed and this is: $6.022\times {{10}^{23}}$.
- Avogadro’s number or Avogadro’s constant is usually denoted by ‘${{N}_{A}}$’. It is the proportionality factor which relates the number of constituent particles or units in a sample with the amount of substance present in that sample.
-Avogadro’s number is fundamental which helps us to understand the makeup of molecules as well as their interactions and combinations.
-Another property of constant term is that the mass of one mole of a substance will always be equal to the molecular weight of that substance.
-This constant term creates a bridge between the macroscopic world and the microscopic world just by relating the amount of substance to the number of particles. It also provides us the relationship between various physical constants and properties.

Note:
-Remember that Avogadro’s number or constant is an important value which is used in mostly all types of measurement calculations, practically as well as theoretically.
-It is mostly used in the mole concept and calculation of concentration terms.
