Specific gravity is a measure of the density of a substance compared to the density of water. It is commonly used to measure the concentration of a liquid, such as alcohol, in a solution. The specific gravity of alcohol-water mixtures can be calculated using the following formula:
Specific gravity = density of solution / density of water
The density of a substance is a measure of how much mass is contained in a certain volume. Water has a density of 1 gram per milliliter (g/mL) at room temperature, so it is used as the reference substance for specific gravity measurements. A substance with a specific gravity greater than 1 is denser than water, while a substance with a specific gravity less than 1 is less dense than water.
Alcohol has a lower density than water, so alcohol-water mixtures will have a specific gravity less than 1. The specific gravity of an alcohol-water mixture will depend on the concentration of alcohol in the mixture. As the concentration of alcohol increases, the specific gravity of the mixture will decrease. For example, a mixture with 50% alcohol by volume will have a specific gravity of around 0.79, while a mixture with 20% alcohol by volume will have a specific gravity of around 0.96.
Specific gravity is an important property of alcohol-water mixtures because it can be used to determine the concentration of alcohol in a solution. This is useful in many applications, such as brewing and distilling, where it is important to control the concentration of alcohol in a mixture. It is also used in the production of alcoholic beverages to ensure that the finished product meets certain quality standards.
In conclusion, specific gravity is a measure of the density of a substance relative to water, and it can be used to calculate the concentration of alcohol in an alcohol-water mixture. The specific gravity of an alcohol-water mixture will depend on the concentration of alcohol in the mixture, with higher concentrations resulting in lower specific gravity values. Specific gravity is an important property in many applications, including brewing, distilling, and the production of alcoholic beverages.

Temperature and Pressure - Online calculator, figures and tables showing density and specific weight of ethanol at temperatures ranging from -25 to 325 °C -10 to 620 °F at atmospheric and higher pressure - Imperial and SI Units. In some cases, more water was added but enough alcohol had been previously removed to bring the contents to 700 cc. Filhol, a substance which is scarcely colored when in solution in acid liquids, but which becomes of a beautiful yellow color when acted on by alkalies. Retrieved 5 May 2007. In other words, it is a measure of how dense a substance is in comparison to water. The observed temperatures were corrected for exposed mercury column by adding C T - t 0. How do you calculate alcohol content? © Mark Biegert and Math Encounters, 2022.
Liquids
This gives it a slightly higher density than water. Temperature - Variations in lubricating oil density as function of temperatur, together with volume correction factors. The boiling point was read when 10 cc. Temperature - Density of Ethyl Alcohol aqueous solutions. Mosses, he says, do not contain it, or, at most, only a trace. This quantity of water would make an error less than 0.

The data for the distillations used in the determination of the mixture boiling with constant composition are all given in graphic form in Fig. Perry, Don Green, Sixth Edition. Temperature and Pressure - Online calculator, figures and tables showing density and specific weight of ethanol at temperatures ranging from -25 to 325 °C -10 to 620 °F at atmospheric and higher pressure - Imperial and SI Units. The value of 0. For example, if your wort had a specific gravity of 1. The two colors are thus iso- lated, and, being retained by two different liquids, cannot be mixed to reproduce the green; but if the liquids are separated and the color- ing matters withdrawn from them, solution in alcohol, which dissolves both, gives immediately a green tint comparable to that of the origi- nal chlorophyll. The author has discovered xanthine in fruits as well as flowers.
