The solubility of methane in C6H12 at 25C is found to be 2.83103 (mole fraction) at 1.013 bar partial pressure of CH4 (Hildebrand and Scott, The Solubility of Nonelectrolytes, 3rd ed, Reinhold, New York, Table 4). (a) If one assumes an ideal mixture and ideal gas, what is the estimated solubility using the Prausnitz/Shair correlation? (b) From the data provided what is the experimental activity coefficient of methane in cyclohexane? (c) Is the regular solution theory consistent with the provided experimental data, i.e., the activity coefficient and solubility
