Why Is "Osmolality" Preferred Over "Osmolarity" as the Measurement of Osmotic

Multiple Choice

Why is "osmolality" preferred over "osmolarity" as the measurement of osmotic activity in the clinical assessment of individuals?

A) Because plasma contains sodium and chloride, which influence the volume of solution
B) Because the volume affects perfusion more than the weight of solutes
C) Because more of the weight of plasma is influenced by solutes, such as protein and glucose, rather than by water
D) Because osmotic activity depends on the concentration of solutes present in plasma, such as proteins and glucose
