All the important formulae relating with mole concept

The following formulas are used in the calculations :

Number of moles (n) = Given number of particles (N) / Avogadro number (N0)

Number of atoms (n) = Given mass (m) / Molar mass (M) x Avogadro number (N0)

Number of molecules (n) = Given mass (m) / Molar mass (M) x Avogadro number (N0)

Number of particles (n) = Number of moles of particles (n) x Avogadro number (N0)
