Applicant's summary and conclusion

Conclusions:
Henry's Law states that at a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid. Henrys Law Constant of 4-fluorophenol which is a solid at 25 deg C is 0.06626655654 Pa m³/mol
Executive summary:

Henrys Law Constant of 4-fluorophenol at 25 deg C is 0.066266557 Pa m³/mol
