A student measures the osmolality of two aqueous solutions, A and B. The student finds that the osmolality of solution B is much higher than solution A. Based on this
result, how do solutions A and B likely differ in the concentration of solutes in their
solution, and why?
1. Solution A likely is the more concentrated solution because osmolality
measures the moles of solute per kilogram of solute.
2. Solution B likely is the more concentrated solution because osmolality
measures the moles of solute per kilogram of solvent.
3. Solution A likely is the more concentrated solution because osmolality
measures the moles of solute per kilogram of solvent.
4. Solution B likely is the more concentrated solution because osmolality
measures the moles of solute per kilogram of solute.
