The corresponding mass percent and mole fraction, x₁, calculated by the compilers are 2.719 × 10^–6 g(1)/100 g sln and 1.841 × 10^–9 assuming a solution density of 1.004 kg/L.

Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   1 L of a 0.5 g/L solution of the hydrocarbon in acetone was distributed over the inside surface of a 1-L round-bottomed flask; the acetone was evaporated with gentle heating. 0.5 L water (or salt water) was added to the dried residue, and the solution was stirred for 6 hr and allowed to settle for 16-18 hr. The upper layer (about 0.3 L) was taken for analysis. The solution was centrifuged twice at 7000 g to remove suspended particles. The hydrocarbon was extracted with benzene and concentrated by evaporation, then purified using thin-layer chromatography. Spectrometric analysis of an octane solution of the hydrocarbon was done using the quasilinear luminescence spectra.
