Specific gravity is important for diagnosing various health conditions, such as dehydration. The normal specific gravity falls between 1.002 - 1.030. Mild dehydration is indicative from specific gravity that is greater than 1.010 and the higher the value the more dehydrated one may be. A 25 year old female patient wastaken to the hospital with symptoms of extreme thirst, fatigue, and headaches. An 0.0077 liter urine sample was taken for the patient described above. The sample had a mass of 8.05 grams.

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
