Experimental Data
The solubility of heptane in water at 16°C was reported to be 0.015 cm3(1)/dm3(2).
With the assumption of a solution density of 1.00 g cm-3 and a density value of 0.6868 g cm-3 for heptane at 16°C (ref 2), the corresponding mass percent is 0.0010 g sln and the corresponding mole fraction, x1, is 1.8 × 10-6 (compiler).
