A quantity that indicates 6.02x10^23 atoms (or molecules)
To make it simple to understand, take a periodic table. Look for example for Carbon. The standard atomic weight is 12. That means one atom of Carbon weighs 12 u (mass atomic units) and a MOLE of atoms of Carbon weighs exactly 12 grams
Tell me if that helped
