Method/Apparatus/Procedure:
About 100-500 mL (2) was placed in a glass cylinder and 10-50 mg of an insoluble indicator was added and (1) was microburetted until the indicator floated to form a colored thin layer on the cylinder wall 2-3 cm above the liquid layer. After each drop of (1), the mixture was vigorously mixed for 0.5-1.5 min.
Source and Purity of Materials:
- Not specified.

Estimated Errors:
Ambient temperature: Not specified.
Components:
- Pentane, $\ce{ C5H12 }$; [109-66-0] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
The solubility of pentane in water at 20°C was reported to be 0.7 g(1) dm-3 (2).
The corresponding mass percent and mole fraction, x1, calculated by the compiler are 0.07 g(1)/100 g sln and 1.7 × 10-4. The assumption that 1 dm3 sln = 1 kg sln was used in the calculations.
