Results and discussion

Henry's Law constant H
H:
0 atm m³/mol
Temp.:
25 °C

Applicant's summary and conclusion

Conclusions:
The Henry's Law constant of the substance is 0.000000001 atm m³/mol.
Executive summary:

The low value of Henry's law constant indicates that sodium saccharin is non-volatile as substantiated by other physico-chemical parameters like vapour pressure, etc
