Description
Density is frequently a quantity divided by volume: mass density or mass concentration is mass per volume, M/V [kg.m-3]; radiant energy density is radiant energy per volume, Q/V [J.m-3]; charge density is charge per volume, Q/V [C.m-3]. However, electric current density is current divided by area, j=I/A [C.m-2]. Number density of entities or number concentration is numbers per volume, CB = NB/V [x.m-3]. In contrast, the amount-of-substance concentration, cB = nB/V [mol.m-3] is not called a substance density (IUPAC). Thus the sample mass concentration is CmX = mX/V [kg.m-3], the mitochondrial concentration is CmtE = mtE/V [mtEU.m-3], whereas the specific mitochondrial density is DmtE = mtE/mX [mtEU.kg-1], and the mitochondrial content per object X is mtENX = mtE/NX [mtEU.x-1] (MitoEAGLE preprint 2018-02-08).
