2. Mole map (chemistry) - Wikipedia

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

   In chemistry, a mole map is a graphical representation of an algorithm that compares molar mass, number of particles per mole, and factors from balanced equations or other formulae. [1] They are often used in undergraduate-level chemistry courses as a tool to teach the basics of stoichiometry and unit conversion. [2] [3] [4]

3. Stoichiometry - Wikipedia

   en.wikipedia.org/wiki/Stoichiometry

   Gas stoichiometry is the quantitative relationship (ratio) between reactants and products in a chemical reaction with reactions that produce gases. Gas stoichiometry applies when the gases produced are assumed to be ideal, and the temperature, pressure, and volume of the gases are all known. The ideal gas law is used for these calculations.

4. Mole (unit) - Wikipedia

   en.wikipedia.org/wiki/Mole_(unit)

   Since its adoption into the International System of Units in 1971, numerous criticisms of the concept of the mole as a unit like the metre or the second have arisen: the number of molecules, etc. in a given amount of material is a fixed dimensionless quantity that can be expressed simply as a number, not requiring a distinct base unit; [ 5 ] [ 24 ]

6. Extent of reaction - Wikipedia

   en.wikipedia.org/wiki/Extent_of_reaction

   This requires that all three mole numbers change according to the stoichiometry of the reaction, but they will not change by the same amounts. However, the extent of reaction ξ {\displaystyle \xi } can be used to describe the changes on a common footing as needed.

7. Equivalent (chemistry) - Wikipedia

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

   The solution has 1 mole or 1 equiv Na +, 1 mole or 2 equiv Ca 2+, and 3 mole or 3 equiv Cl −. An earlier definition, used especially for chemical elements , holds that an equivalent is the amount of a substance that will react with 1 g (0.035 oz) of hydrogen , 8 g (0.28 oz) of oxygen , or 35.5 g (1.25 oz) of chlorine —or that will displace ...

8. Amount of substance - Wikipedia

   en.wikipedia.org/wiki/Amount_of_substance

   Historically, the mole was defined as the amount of substance in 12 grams of the carbon-12 isotope.As a consequence, the mass of one mole of a chemical compound, in grams, is numerically equal (for all practical purposes) to the mass of one molecule or formula unit of the compound, in daltons, and the molar mass of an isotope in grams per mole is approximately equal to the mass number ...

9. Molar mass - Wikipedia

   en.wikipedia.org/wiki/Molar_mass

   The mole was defined in such a way that the molar mass of a compound, in g/mol, is numerically equal to the average mass of one molecule or formula unit, in daltons. It was exactly equal before the redefinition of the mole in 2019 , and is now only approximately equal, but the difference is negligible for all practical purposes.
