mass concentration the mass of a constituent substance divided by the volume of the mixture, as milligrams per liter (mg/l).
mean corpuscular hemoglobin concentration (MCHC) the average hemoglobin concentration in erythrocytes, conventionally expressed in “per cent,” meaning grams per deciliter of red blood cells, obtained by dividing the blood hemoglobin concentration (in g/dl) by the hematocrit (in l/l): MCHC = Hb/Hct.

(mō'lăr), Do not confuse this word with molal.
1. Denoting a grinding, abrading, or wearing away.
2. Synonym(s): molar tooth
3. Massive; relating to a mass; not molecular.
4. Denoting a concentration of 1 g.-molecular weight (1 mol) of solute per liter of solution, the common unit of concentration in chemistry. Compare: molal.

The reaction rate of [H.sub.2]S[O.sub.4] was slowed down when the molar concentration of [H.sub.2]S[O.sub.4] was 0.5 M.
In order to produce the most accurate Lp(a) mass measurement that is independent of apo(a) size, thus allowing an accurate report of Lp(a) mass in units of molar concentration (i.e., particle number), it is recommended that Lp(a) mass assays eventually update their methodology by using a monoclonal detection antibody directed against a constant Lp(a) domain such as apo(a) Kringle 4 type 8 or 9.
The slope (ratio of molar concentration over peak area) for R-32, R-134a, and R-125 were 8.14 x [10.sup.-5], 5.96 x [10.sup.-5], 5.68 x [10.sup.-5] (Figure 8).
