Answer 2

(a) n=N/N₀ represents the correct relation between Avogadro's number(N₀), number of particles(N) and moles(n).

Explanation:

• The number of electrons, atoms, ions or molecules in one mole of substance is known as Avogadro's number.
• The Avogadro's number can be written as 6.022× 10²³ mol⁻¹.
• Number of moles can be found by dividing the number of atoms and Avogadro number.
• The number of moles can be represented as n=N/N₀.
• The relation between Avogadro number, number of particles, number of moles can be changed as, N=n × N₀.
• In 1 mole of substance, the number of particles presented is fixed.
