Answer
Too much sugar makes the urine more dense than usual while too much water makes the urine less dense than usual.
Work Step by Step
The change in volume of a water solution is negligible compared to the change in mass caused by a change in the concentration of a solute, like sugar. Therefore, if the urine has more sugars than usual, it has more mass per unit volume; if it has more water than usual, it has less mass per unit volume.
