Question

The definition of osmolality is the __________ the contrast agent solution.

a. thickness of
b. measure of dissociation of
c. concentration of molecular particles in
d. rate of injection of

Answer 1

Osmolality is the measure of the concentration of molecular particles in a solution. It is the ratio of solutes to the volume of solvent in a solution. Osmolarity is a way of reporting the total number of particles in a solution to determine osmotic pressure.

Step-by-step explanation:

Osmolality is the measure of the concentration of molecular particles in a contrast agent solution. It is the ratio of solutes to the volume of solvent in a solution. Osmolarity, on the other hand, is a way of reporting the total number of particles in a solution to determine osmotic pressure. The two terms are related but differ in the units of measurement. Osmolality measures the moles of solute per kilogram of solvent, while osmolarity measures the molarity of a solute times the number of particles a formula unit of the solute makes when it dissolves.
