It is necessary to estimate the solubility of a poison gas (1) in water (2) at 2

Question

It is necessary to estimate the solubility of a poison gas (1) in water (2) at 25 C and a partial pressure of the gas of 0.5 atm. A hypothetical poison gas vapor pressure at 25 C equal to 1000 atm can be assumed and the fugacity coefficient correction can be neglected. 1) Calculate the mole fraction of the gas in water assuming that they form an ideal solution. 2) From regular solution theory has been estimated that ln 1L = 0.526(1-x1)2; what is the equilibrium mol fraction of the gas in water under these circumstances. 3) What is the Henry’s law constant for this system?
