Key Concepts

1 mole of any substance contains 6.022 × 1023 particles.

6.022 × 1023 is known as the Avogadro Number or Avogadro Constant and is given the symbol NA(1)

N = n × NA

N = number of particles in the substance

n = amount of substance in moles (mol)

NA = Avogardro Number = 6.022 × 1023 particles mol-1

N = n × (6.022 × 1023)

To find the number of particles, N, in a substance:

N = n × NA

N = n × (6.022 × 1023)

To find the amount of substance in moles, n :

n = N ÷ NA

n = N ÷ (6.022 × 1023)
