Correct Answer Avogadro made a distinction between atoms and molecules.

Key PointsAvogadro is a term that refers to two related concepts in chemistry:

Avogadro's number:

  • This is a fundamental constant in chemistry that represents the number of atoms or molecules in one mole of a substance. (Option 4 is correct)
  • Its value is approximately 6.022 x 10^23, and it is denoted by the symbol "N_A".
  • Avogadro's number is a key concept in stoichiometry. 
  • The branch of chemistry deals with the quantitative relationships between reactants and products in chemical reactions.

Amedeo Avogadro:

  • He is best known for his contributions to the development of the mole concept in chemistry.
  • Avogadro proposed that equal volumes of gases at the same temperature and pressure contain the same number of particles, which led to the development of Avogadro's law.
  • He also proposed the hypothesis that the same volume of different gases, at the same temperature and pressure, contains an equal number of molecules. This hypothesis became known as Avogadro's principle.
  • Avogadro's contributions to the development of the mole concept and the understanding of the behavior of gases have had a profound impact on the field of chemistry.
