Reason for chemists to define the mole in this manner should be discussed. Concept Introduction: According to Avogadro theory, sample in which the ratio of the masses is the same as the ratio of the masses of the individual atoms always contain the same number of atoms. If we weigh out samples of all the elements such that each sample has a mass equal to its average atomic mass in grams, these samples all contain the same number of atoms. This number is called the Avogadro’s number and equals to 1 mole.Start your trial now! First week only $4.99!*arrow_forward*

Interpretation Introduction

**Interpretation:**

One mole of a substance represents on a microscopic, atomic basis and macroscopic, mass basis should be explained. Reason for chemists to define the mole in this manner should be discussed.
