What is the density of urine?

Answer 1

The physical properties and chemical composition of urine are very variable and are determined in large measure by the quantity and the type of food consumed. The specific gravity is the ratio of the density to that of water, and it is dependent on the number and weight of solute particles and on the temperature of the sample. The weight of solute particles is constituted mainly of urea (73 %), chloride (5.4 %), sodium (5.1 %), potassium (2.4 %), phosphate (2.0 %), uric acid (1.7 %), and sulfate (1.3 %). The density of the liquid urine is arround 1,025 kg/m³. That is close to water.

Answer 2

The weight of urine is very similar to water because it is composed of 95% water. A gallon of urine weighs about 8.3 pounds.

Urine is weighed in specific gravity--measures how diluted or concentrated the urine is.
