Branch copper content per branch dry mass

Formal name:  branch copper content per branch dry mass
Local identifier:  TOP417
Synonym Term:  branch Cu content per dry mass
Related Term:  branch Cu content
Related Term:  branch Cu concentration
Definition:  The ratio of the quantity (SEP:quantity) of copper (CHEBI:copper atom) in the branch (PO:branch) to the corresponding branch (PO:branch) mass (PATO:mass) assessed after drying
Formal Unit:  mass unit / mass unit or amount unit / mass unit

Comment:  The quantity of copper can be expressed either as a mass (with mass unit, e.g. gram) or as an amount (with amount unit, e.g. mol). The term concentration is polysemic and we suggest to not use it in this context.
