Specific gravity, ratio of the density of a substance to that of a standard substance. Solids and liquids are often compared with water at 4 C, which has a density of 1.0 kg per liter. Gases are often compared with dry air, having a density of 1.29 grams per liter (1.29 ounces per cubic foot) under standard conditions.

Specific gravity is used by mineralogists and geologists to determine the mineral content of the rock. Urinary specific gravity is a measure of the concentration of solutes in the urine. The test is a routine part of a urinalysis. For better understanding, you might want to check out the following articles:

Because the concentration is a percent, you know a 100-gram sample would contain 12 grams of iron. You can set this up as an equation and solve for the unknown "x": 12 g iron / 100 g sample = x g iron / 250 g sample. Cross-multiply and divide: x= (12 x 250) / 100 = 30 grams of iron.

The principal organic acids found in grapes are tartaric, malic, and to a small extent, citric. Many other organic acids, including amino acids, are also found in juice and wines, but tartaric and malic acid account for over 90% of the total acids present. During the early period of berry growth, concentration of both acids increases in the fruit.
