Understanding Moles

What is a Mole?

A mole is the amount of substance containing exactly 6.02214076 × 10²³ elementary entities. This number is known as Avogadro's constant (NA).

Key Relationships

Important mole relationships:

  • 1 mole = 6.02214076 × 10²³ particles
  • Moles = mass / molar mass
  • Mass = moles × molar mass
  • Particles = moles × NA

Applications

The mole concept is essential in:

  • Stoichiometric calculations
  • Solution preparation
  • Gas law calculations
  • Chemical analysis

Common Conversions

Useful conversion factors:

  • 1 mole of any gas = 22.4 L (at STP)
  • 1 mole of water = 18.02 g
  • 1 mole of NaCl = 58.44 g
