Using the weight of alcohol and the total weight, we can easily determine the alcohol-by-weight (also expressed as a number between 0 and 1): abw = 0.789 * abv / (1 - 0.211 * abv) So this is clearly not linear (it is hyperbolic ), and maintains identity for the 0% and 100% cases as expected.
At relatively low alc/vol, the alcohol percentage by weight is about 4/5 of the alc/vol (e.g., 3.2% ABW is about 4% alc/vol). [24] However, because of the miscibility of alcohol and water, the conversion factor is not constant but rather depends upon the concentration of alcohol.
30 sty 2023 · Equivalent weight is the ratio of molecular mass and valence factor. It can be calculated by knowing the valence factor for acids and bases, which are the number of replaceable hydrogen and hydroxyl groups, respectively.
21 maj 2024 · ABW — Alcohol by weight, measured in percent; OE — Original extract (before fermentation), measured in Plato degrees (°P); and; AE — Apparent extract (after fermentation). From this alcohol formula, they derived an equation for alcohol by volume: ABV = ABW × (1.308 × 10-5 + 3.868 × 10-3 × AE + 1.275 × 10-5 × AE 2 + 6.3 × 10-8 × ...
8 mar 2020 · The general number of equivalents formula is. E = MW/charge number. Where MW is the molecular weight of the compound and charge number is the number of proton- or hydroxide-equivalents the compound contains. Examples with different acids and bases help illustrate how this works in practice.
Summary. The equivalent masses of acids, bases, and salts are calculated as follows: Equivalent mass of an acid = molecular mass of the acid/basicity. Equivalent mass of a base = molecular mass of the base/acidity. Equivalent mass of a salt = molecular mass of the salt/total positive valency of metal atoms.
