  5. Molecular mass - Wikipedia

    en.wikipedia.org/wiki/Molecular_mass

    The molecular mass (m) is the mass of a given molecule. Units of daltons (Da) are often used. [1] Different molecules of the same compound may have different molecular masses because they contain different isotopes of an element.

  6. Extent of reaction - Wikipedia

    en.wikipedia.org/wiki/Extent_of_reaction

    In physical chemistry and chemical engineering, extent of reaction is a quantity that measures the extent to which the reaction has proceeded. Often, it refers specifically to the value of the extent of reaction when equilibrium has been reached.

  8. Air–fuel ratio - Wikipedia

    en.wikipedia.org/wiki/Air–fuel_ratio

    Air–fuel equivalence ratio, λ (lambda), is the ratio of actual AFR to stoichiometry for a given mixture. λ = 1.0 is at stoichiometry, rich mixtures λ < 1.0, and lean mixtures λ > 1.0. There is a direct relationship between λ and AFR. To calculate AFR from a given λ, multiply the measured λ by the stoichiometric AFR for that fuel.
