separate parameters components

[Stemanzo91]

Good morning.
I tried to search in the forum but nn I managed to find an answer.
I would like to make appear in my distinct components of a set the total mass of each part I created the column mass tot but I can not understand how to make a relationship between qtà and mass to go to fill the column mass tot.
I attach photos.
