In chemistry, the mass concentration ρ i (or γ i) is defined as the mass of a constituent m i divided by the volume of the mixture V. [1]= For a pure chemical the mass concentration equals its density (mass divided by volume); thus the mass concentration of a component in a mixture can be called the density of a component in a mixture.
Alcohol by volume (abbreviated as alc/vol or ABV) is a standard measure of the volume of alcohol contained in a given volume of an alcoholic beverage, expressed as a volume percent. [ 1 ] [ 2 ] [ 3 ] It is defined as the number of millilitres (mL) of pure ethanol present in 100 mL (3.5 imp fl oz; 3.4 US fl oz) of solution at 20 °C (68 °F).
It is the same concept as volume percent (vol%) except that the latter is expressed with a denominator of 100, e.g., 18%. The volume fraction coincides with the volume concentration in ideal solutions where the volumes of the constituents are additive (the volume of the solution is equal to the sum of the volumes of its ingredients).
V d is the volume of distribution (L); typically body weight (kg) multiplied by 0.71 L/kg for men and 0.58 L/kg for women [32] [33] although estimation using TBW is more accurate. [34] A standard drink, defined by the WHO as 10 grams of pure alcohol, [35] is the most frequently used measure in many countries. Examples: A 80 kg man drinks 20 ...
Alcohol measurements are units of measurement for determining amounts of beverage alcohol.Alcohol concentration in beverages is commonly expressed as alcohol by volume (ABV), ranging from less than 0.1% in fruit juices to up to 98% in rare cases of spirits.

In terms of density, m = ρV, where ρ is the volumetric mass density, V is the volume occupied by the mass. This energy can be released by the processes of nuclear fission (~ 0.1%), nuclear fusion (~ 1%), or the annihilation of some or all of the matter in the volume V by matter–antimatter collisions (100%).

For volume fraction, the suffix "V" or "v" is sometimes appended to the parts-per notation (e.g. ppmV, ppbv, pptv). [ 8 ] [ 9 ] However, ppbv and pptv are usually used to mean mole fractions – "volume fraction" would literally mean what volume of a pure substance is included in a given volume of a mixture, and this is rarely used except in ...
