Applicant's summary and conclusion

Conclusions:
The density of the test item at 20ºC was 1.83 g/cm3 (1.83 × 103 kg/m3).
The relative density was 1.83.
Executive summary:

A pycnometer was used for the determination of the density and relative density of Sodium hypoxanthine.

The density of the test item at 20ºC was 1.83 g/cm3 (1.83 × 103 kg/m3).

The relative density was 1.83.
