2. Mass concentration (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Mass_concentration_(chemistry)

   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.

3. Volume fraction - Wikipedia

   en.wikipedia.org/wiki/Volume_fraction

   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). The sum of all volume fractions of a mixture is equal to 1:

4. Mass fraction (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Mass_fraction_(chemistry)

   The very ambiguous terms percent solution and percentage solutions with no other qualifiers continue to occasionally be encountered. In thermal engineering, vapor quality is used for the mass fraction of vapor in the steam. In alloys, especially those of noble metals, the term fineness is used for the mass fraction of the noble metal in the alloy.

5. Dilution (equation) - Wikipedia

   en.wikipedia.org/wiki/Dilution_(equation)

   Dilution is the process of decreasing the concentration of a solute in a solution, usually simply by mixing with more solvent like adding more water to the solution. To dilute a solution means to add more solvent without the addition of more solute. The resulting solution is thoroughly mixed so as to ensure that all parts of the solution are ...

6. Solution (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Solution_(chemistry)

   Making a saline water solution by dissolving table salt in water.The salt is the solute and the water the solvent. In chemistry, a solution is defined by IUPAC as "A liquid or solid phase containing more than one substance, when for convenience one (or more) substance, which is called the solvent, is treated differently from the other substances, which are called solutes.

7. Parts-per notation - Wikipedia

   en.wikipedia.org/wiki/Parts-per_notation

   In fractions like "2 nanometers per meter" (2 n m / m = 2 nano = 2×10 −9 = 2 ppb = 2 × 0.000 000 001), so the quotients are pure-number coefficients with positive values less than or equal to 1. When parts-per notations, including the percent symbol (%), are used in regular prose (as opposed to mathematical expressions), they are still pure ...

8. Concentration - Wikipedia

   en.wikipedia.org/wiki/Concentration

   The solutions on the left are more dilute, compared to the more concentrated solutions on the right. Often in informal, non-technical language, concentration is described in a qualitative way, through the use of adjectives such as "dilute" for solutions of relatively low concentration and "concentrated" for solutions of relatively high ...

9. Equivalent concentration - Wikipedia

   en.wikipedia.org/wiki/Equivalent_concentration

   Here, ⁠ 1 / f eq ⁠ can have a fractional (non-integer) value. In precipitation reactions, the equivalence factor measures the number of ions which will precipitate in a given reaction. Here, ⁠ 1 / f eq ⁠ is an integer value. Normal concentration of an ionic solution is also related to conductivity (electrolytic) through the use of ...
