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.

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?
To determine the density of urine using a urinometer, you simply place the urinometer in a container of urine and allow it to float. The reading is taken at the point where the surface of the urine intersects with the scale on the urinometer. The density of the urine is then determined by comparing this reading to a known scale.
Three 10mL samples of urine weigh 10.01g 10.20g and 10.36g respectively Which sample represents normal urine in terms of density?
The density of normal urine is around 1.010 g/mL. Comparing the weights to volumes, the first sample has a density of 1.001 g/mL, the second has a density of 1.020 g/mL, and the third has a density of 1.036 g/mL. Therefore, the second sample with a density of 1.020 g/mL represents normal urine in terms of density.
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 ?
What will alcohol do to the density of urine?
Alcohol can decrease the production of antidiuretic hormone (ADH), which can lead to increased urine output and decreased urine density. This can result in dilute urine with lower density when alcohol is consumed.
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 density of a urine sample if a 15 mililitersample has a mass of 16.2grams?
16.2/15 = 1.08 gram per ml
What indicates the amount of dissolved substance in the urine?
The specific gravity of urine indicates the amount of dissolved substances in urine. It is a measure of the density of urine compared to water. A higher specific gravity indicates a higher concentration of dissolved substances, while a lower specific gravity indicates a lower concentration.
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.
If human urine is 1.8 percent urea how many grams of urea are present in 50 ml of urine?
To calculate the grams of urea in 50 ml of urine where 1.8% is urea, first convert the ml to grams using the density of urine (about 1 g/ml). Then, multiply the volume of urine in grams by the percentage of urea (0.018) to find the grams of urea present in 50 ml of urine.
