Experimental Values:
The solubility of n-heptane in water at 100°F (311 K) was reported to be < 0.1 g(1)/100 g sl. The corresponding mole fraction, x1, calculated by the compiler, is < 2 × 10-4.
The solubility of water in n-heptane at 100°F (311 K) was reported to be 0.12 g(2)/100 g sln. The corresponding mole fraction, x2, calculated by the compiler, is 6.6 × 10-3.
