Methodology:
The method consisted of preparing serial dilutions of a suspension of [1] in [2] and determining nephelometrically the amount of [1] per unit volume beyond which further dilution caused no reduction in light scattering, which remained equal to that of pure [2]. A Bausch and Lomb Dubosque colorimeter model 100-mm was employed. Many details are reported in [1].
Sample Information:
- Prepared at Harvard University; MP = 140.0-140.5°C (cf. [2]).
- Dust-free.
Measurement Errors:
Ambient temperature: ±3°C
Mass concentration (m/v) (1): ±0.5 × 10-5 g(1) dm-3(2)

System Components:
- 10-Methylbenz[a]anthracene, $\ce{ C19H14 }$; [2381-15-9] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
The solubility of 10-methylbenz[a]anthracene in water at 27°C was reported to be 5.5 × 10-5 g(1) L-1(2).
(Four identical results have been obtained)
With the assumption that 1.00 L sln = 1.00 kg sln, the corresponding mass percent and mole fraction, x1, calculated by the compiler are 5.5 × 10-6 g(1)/100 g sln and 4.1 × 10-11.
