Method/Apparatus/Procedure:
A test tube containing (1) was placed in a flask containing (2) thus allowing for equilibration through the vapor phase. The saturated solution was extracted with hexane and analyzed by gas chromatography.
Source and Purity of Materials:
- From either Aldrich Chemical Co. or Matheson Coleman and Bell, 99+% pure.
- made from doubly distilled water and salts 99+% pure.
Estimated Errors:
Ambient temperature: ±0.1 K
Mass concentration (m/v) (1): 2.8 (std. dev.)

Experimental Data
The solubility of toluene in artificial seawater is reported to be 379.3 mg(1)/kg sln. The corresponding mass percent and mole fraction, x1 calculated by the compiler are 0.3793 g(1)/100 g sln and 7.61 × 10-5 assuming the artificial seawater composition of ref 1.
