A mole is #6.02*10^23# (avogadro's number) molecules of a substance. The molar mass is the amount of mass that 1 mole of that substance possesses.


The amount of molecules of any substance to make 1 mole is constant.
However, due to differing atomic masses, different molecules will have different molar masses.

If you have #6.02*10^23# feathers and #6.02*10^23# bricks, you have 1 mole of each, but the bricks have a lot more mass.
