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.

∙ 8y agoThe 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.

Why is the density of urine greater than the density of water?
Urine contain more solutes.
What does the specific gravity (SG) of urine measure?
The density of urine
What reflects the amount of wastes minerals and solids in urine?
Your urine's specific gravity reflects the amount of minerals, solids, and wastes in the urine. Specific gravity is a comparison of urine's density to water's density.
Explain the method of determining the density of urine using urinometer?
A urinometer is a device that determines the specific gravity of urine. It is placed in a urine tube, and where the meniscus of the urine reaches, it is considered its specific gravity.
Urine has a Mass of 122 g and a Volume of 121 mL what is the density?
Mass of urine=122g volume = 121 ml density in g/ml ?
An important characteristc of urine is its specific gravity or density which is?
1.001-1.035
How do you calculate the liquid pressure?
By using a device called manometers.
A urine test that compares the weight of urine to that of distilled water is?
Specific gravity (SG) is a measurement of the kidneys' ability to concentrate urine. The test compares the density of urine against the density of distilled water, which has an SG of 1.000. Because urine is a solution of minerals, salts, and compounds dissolved in water, the SG is a measure of the density of the dissolved chemicals in the specimen. As a measurement of specimen density, SG is influenced by both the number of particles present and the size of the particles. Osmolality is a more exact measurement and may be needed in certain circumstances. The range of urine SG depends on the state of hydration and varies with urine volume and the load of solids to be excreted under standardized conditions; when fluid intake is restricted or increased, SG measures the concentrating and diluting functions of the kidney. Loss of these functions is an indication of renal dysfunction. http://faculty.washington.edu/alexbert/MEDEX/Spring/TS3UA.htm
What is the examination of the physical and chemical properties of urine?
Some analysis on urine: - density - pH - ketones - calcium - phosphate - vitamin C - blood cells - bilirubin - creatinin - bacterias etc.
What is the density of a urine sample if a 15 mililitersample has a mass of 16.2grams?
16.2/15 = 1.08 gram per ml
Three 10mL samples of urine weigh 10.01g 10.20g and 10.36g respectively Which sample represents normal urine in terms of density?
10.20 g sample is normal, with a specific gravity of 1.020.
What has the greater specific gravity 1 milliliter of urine or 1 milliliter of distilled water?
The urine volume density is usually 1006 - 1022 kg/m3, water is 998,205 kg/m3 at 20 Centigrade. Urine has grater gravity than water.
