What is the value of the Avogadro constant?

• A. 6.02 x 10²²
• B. 6.02 x 10²³
• C. 6.02 x 10²⁴
• D. 6.02 x 10²⁵

Answer: (B)

The Avogadro constant is a fundamental quantity in chemistry, defined as the number of particles (atoms, molecules, or ions) in one mole of a substance. This constant is crucial for converting between the amount of substance in moles and the number of individual particles, enabling chemists to accurately quantify and relate chemical reactions. The value of the Avogadro constant is approximately 6.02 x 10²³, which is widely accepted in scientific literature. This number stems from the mole definition, which relates macroscopic measurements of matter to microscopic quantities, thereby facilitating calculations in stoichiometry and chemical equations. The other values listed, such as 6.02 x 10²², 6.02 x 10²⁴, and 6.02 x 10²⁵, do not accurately represent the number of particles in a mole, making them incorrect. These figures do not align with established scientific understanding or experimental measurements related to chemical quantities.
