Question

plz tell me some important formulae of mole concept?

Answer 1

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

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

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

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

I hope these formulas are helpful to u. IF s then pls mark as brainiest.
