Understanding Atoms and Moles

What is Avogadro's Constant?

Avogadro's constant (NA) is 6.02214076 × 10²³ particles per mole. This fundamental physical constant represents the number of constituent particles (atoms, molecules, ions, or other particles) in one mole of a substance.

Converting Between Atoms and Moles

To convert atoms to moles, divide the number of atoms by Avogadro's constant:

Moles = Number of Atoms ÷ (6.02214076 × 10²³)

To convert moles to atoms, multiply the number of moles by Avogadro's constant:

Number of Atoms = Moles × (6.02214076 × 10²³)

Applications in Chemistry

Understanding the relationship between atoms and moles is crucial in chemistry for:

  • Balancing chemical equations
  • Calculating reaction yields
  • Determining concentrations
  • Preparing solutions
