Experimental Data
The solubility of water in toluene at 25°C was reported to be 0.0268 mol (2) dm-3 sln.
The corresponding mass percent and mole fraction, x1, calculated by the compilers are 0.0560 g(2)/100 g sln and 2.86 × 10-3. The assumption that 1 dm3 sln = 863 g sln was used in the calculation.
