The number of particles (molecules/atoms) is equal to its relative atomic or relative molecular mass multiplied by avogadros constant.

Mr x Moles=mass you mean?
with Avogadro constant you are finding the number of particles by multiplying by the number of moles.

Don't do that in the exam! :smile:
So Molar mass * moles = mass and N = avogadros constant * moles?

If N means number of particles of a specific species then yes.
