What’s the number of entities or particles together in mole concept

1.	What’s the number of entities or particles together in mole concept known as?(a) Boltzmann constant(b) Avogadro’s number(c) Universal gas constant(d) Reynold’s numberI got this question in class test.I need to ask this question from Mole Concept and Molar Masses in portion Chemistry Basic Concepts of Chemistry – Class 11
Answer» Correct CHOICE is (b) Avogadro’s number The explanation is: Avogadro number DENOTED by NA. Its VALUE is 602213670000000000000000, also written as 6.022×10^23. It’s the number of ENTITIES in 1 mol of a substance. The units may be electrons, atoms, ions, or molecules, depending on the NATURE of the substance.
