**Question**

**The number of mole (n), the number of particles (N) and the Avogadro number (N) and the Avogadro Number (N _{A}) are related as**

**n = N_A\over N****N\over N_A = N****n = N\over N_A****n = N.N**_{A}

**Answer**

n = N / N_{A}

**Explanation**

The correct equation relating the number of moles (n), the number of particles (N), and Avogadro’s number (NA) is:

N = n × N_{A}
