Understand the Problem
The question is asking about the concepts of the mole and Avogadro's number, which are fundamental concepts in chemistry related to the measurement of substance quantities.
Answer
Avogadro's number is 6.022 × 10²³.
The Avogadro's number is 6.022 × 10²³ and represents the number of units (atoms, molecules, ions, etc.) in one mole of a substance.
Answer for screen readers
The Avogadro's number is 6.022 × 10²³ and represents the number of units (atoms, molecules, ions, etc.) in one mole of a substance.
More Information
Named after Amedeo Avogadro, Avogadro's number is fundamental to understanding quantities in chemistry. It allows chemists to count particles in a given sample using the concept of the mole.
Tips
A common error is to misinterpret or misapply exponential notation, especially in conversions that involve Avogadro's number.
