+12 The density of urine ranges from 1.01 g/ml to 1.03 g/ml.
a. What is the density of a 0.75 liter urine sample that has a mass of 765 g?
b. Why can urine density change?
+36915 Let's use consistent units .75 l = 750ml
Density = mass/volume = 765 gm / 750 ml = 1.02 gm/ml
Urine density can change by the kindneys increasing the concentration....by excreting more salt ...or re-absorbing more water.
or decreasing the concentration by holding salt and excreting more water....
