It is often necessary to convert concentration data from molarity tomolality and vice versa. This conversion is used for the correction and extrapolationof equilibrium data to zero ionic strength by the specific ion interaction theory whichworks in molality units (cf. Appendix B). This conversion is made in the following way.Molality is defined as m B moles of substance B dissolved in 1000 grams of pure water.Molarity is defined as c B moles of substance B dissolved in (1000ρ − c B M) grams ofpure water, where ρ is the density of the solution and M the molar weight of the solute.From this it follows thatm B =1000c B1000ρ − c B MTable 2.4: Unit conversion factorsTo convert from to multiply by(non-SI unit symbol)(SI unit symbol)ångström (Å) metre (m) 1 × 10 −10 (exactly)standard atmosphere (atm) pascal (Pa) 1.01325 × 10 5 (exactly)bar (bar) pascal (Pa) 1 × 10 5 (exactly)thermochemical calorie (cal) joule (J) 4.184 (exactly)entropy unit (e.u. ∧ = cal · K −1 · mol −1 ) J · K −1 · mol −1 4.184 (exactly)
