Not really clear what is meant here. If I grain the Calciumnitride I can get a lot of particles depending on the grain size.
The formula is Ca3N2. You can calculate the mole from the given mass. 1 mol is 6,023x10^23 particles.

A sample of Calcium Nitride Ca
3N
2 📖having a mass 6.78 grams have 2.75e22 atoms which is= 0.0457 mole.

Calculation is wrong. Molar mass of Ca3N2 is 148 g/mol.
6,78 g is then 6,78g/148 g/mol = 0,00452 mol what guids to 2,76 x 10^22 particles.

I am sorry. I computed for CH₃N₂. I shall edit my answer now.
Thanks for finding out error in the computation
