  2. Molar concentration - Wikipedia

    en.wikipedia.org/wiki/Molar_concentration

    In chemistry, the most commonly used unit for molarity is the number of moles per liter, having the unit symbol mol/L or mol/dm 3 in SI units. A solution with a concentration of 1 mol/L is said to be 1 molar, commonly designated as 1 M or 1 M.

  3. Orders of magnitude (molar concentration) - Wikipedia

    M denotes the non-SI unit molar: 1 M = 1 mol/L = 10 −3 mol/m 3. All orders ... 1 M: standard state concentration for defining thermodynamic activity [21] 10 1: daM ...

  4. Molar absorption coefficient - Wikipedia

    en.wikipedia.org/wiki/Molar_absorption_coefficient

    The SI unit of molar absorption coefficient is the square metre per mole (m 2 /mol), but in practice, quantities are usually expressed in terms of M1 ⋅cm −1 or Lmol1 ⋅cm −1 (the latter two units are both equal to 0.1 m 2 /mol). In older literature, the cm 2 /mol is sometimes used; 1 M1 ⋅cm −1 equals 1000 cm 2 /mol.

    [1] To convert from L 2 b a r / m o l 2 {\displaystyle \mathrm {L^{2}bar/mol^{2}} } to L 2 k P a / m o l 2 {\displaystyle \mathrm {L^{2}kPa/mol^{2}} } , multiply by 100. To convert from L 2 b a r / m o l 2 {\displaystyle \mathrm {L^{2}bar/mol^{2}} } to m 6 P a / m o l 2 {\displaystyle \mathrm {m^{6}Pa/mol^{2}} } , divide by 10.

  6. Reaction rate constant - Wikipedia

    en.wikipedia.org/wiki/Reaction_rate_constant

    Here, c ⊖ is the standard concentration, generally chosen based on the unit of concentration used (usually c ⊖ = 1 mol L1 = 1 M), and M is the molecularity of the transition state. Lastly, κ, usually set to unity, is known as the transmission coefficient , a parameter which essentially serves as a " fudge factor " for transition state ...

  7. Mole (unit) - Wikipedia

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

    Chemical engineers once used the kilogram-mole (notation kg-mol), which is defined as the number of entities in 12 kg of 12 C, and often referred to the mole as the gram-mole (notation g-mol), then defined as the number of entities in 12 g of 12 C, when dealing with laboratory data. [6]

    The SI unit is mol/m 3. However, more commonly the unit mol/L (= mol/dm 3) is used. Number concentration. The number concentration is defined ...

  9. Ionic strength - Wikipedia

    en.wikipedia.org/wiki/Ionic_strength

    The molar ionic strength, I, of a solution is a function of the concentration of all ions present in that solution. [3]= = where one half is because we are including both cations and anions, c i is the molar concentration of ion i (M, mol/L), z i is the charge number of that ion, and the sum is taken over all ions in the solution.
