Applicant's summary and conclusion

Conclusions:
The HL constant was 0.000298 Pa m³/mol.
Executive summary:

Henry's Law constant was calculated using EQUATION R.16-4 (Henry = (VP*MW)/Solubility) in the REACH guidance R.16. Input values were vapour pressure (3.91 Pa), solubility (1E6 mg/L), and MW (76.10 g/mol). The HL constant was 0.000298 Pa m³/mol.
