Bark copper content per bark dry mass

Formal name:  bark copper content per bark dry mass
Local identifier:  TOP379
Synonym Term:  bark Cu content per dry mass
Related Term:  bark Cu concentration

Definition:  The ratio of the quantity (SEP:quantity) of copper (CHEBI:copper atom) in the bark (PO:bark) to the corresponding bark (PO:bark) 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.
