Bark sodium content per bark dry mass

Formal name:  bark sodium content per bark dry mass
Local identifier:  TOP384
Synonym Term:  bark Na content per dry mass
Related Term:  bark Na content

Definition:  The ratio of the quantity (SEP:quantity) of sodium (CHEBI:sodium 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 sodium 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.
