Change in volume with increasing alc/vol. Mixing two solutions of alcohol of different strengths usually causes a change in volume. Mixing pure water with a solution less than 24% by mass causes a slight increase in total volume, whereas the mixing of two solutions above 24% causes a decrease in volume.
A liquid just alcoholic enough to maintain combustion was defined as 100 proof and was the basis for taxation. Because the flash point of alcohol is highly dependent on temperature, 100 proof defined this way ranges from 20% at 36 °C (97 °F) to 96% at 13 °C (55 °F) alcohol by weight; at 24 °C (75 °F) 100 proof would be 50% ABW.

It is important, where any conversion to °P is involved, that the proper pair of temperatures be used for the conversion table or formula being employed. The current ASBC table is (20 °C/20 °C) meaning that the density is measured at 20 °C (68 °F) and referenced to the density of water at 20 °C (68 °F) (i.e. 0.998203 g/cm 3 or 0.0360624 ...
A basic formula [4] to calculate beer strength based on the difference between the original and final SG is: A B V = 131.25 ( O G − F G ) {\displaystyle ABV=131.25(OG-FG)} The formula below [ 5 ] is an alternate equation which provides more accurate estimates at higher alcohol percentages (it is typically used for beers above 6 or 7%).
4% ABV beer is equivalent to 3.2% ABW beer. ABV is 5/4 of the ABW at low ABV, as the relationship is not linear. Wahrmund 04:26, 2 May 2009 (UTC) Thank you for the explanation. That makes sense now. Maybe it is because it switches between using ABV for one and "Alcohol by weight" instead of using the acronym for both.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering.They are described as ratios of how much of a reactant has reacted (X — conversion, normally between zero and one), how much of a desired product was formed (Y — yield, normally also between zero and one) and how much desired product was formed in ratio to the undesired product(s) (S ...
In chemistry, the mass fraction of a substance within a mixture is the ratio (alternatively denoted ) of the mass of that substance to the total mass of the mixture. [1] Expressed as a formula, the mass fraction is:
