What is Avogadro's number approximately equal to?

• A. 6.02 x 10^23
• B. 3.00 x 10^23
• C. 1.50 x 10^23
• D. 9.11 x 10^23

Answer: (A)

Avogadro's number is the number of particles in one mole, serving as the bridge between the microscopic and macroscopic realms in chemistry. By definition, one mole contains 6.022×10^23 particles (atoms, molecules, or ions). We round that to 6.02×10^23 for practical calculations. That fixed constant lets you convert between the amount of substance in moles and the actual count of particles. The other numbers are not used as the standard conversion factor because they are far from this defined value, so they don’t correctly represent the quantity of particles per mole.
