Applicant's summary and conclusion

Conclusions:
Using the pycnometer method. a density of 1.8219 ± 0.0007 g/cm3 at 20 ± 0.2 °C was measured.
This value is the mean of two independent determinations with the maximum error of a single determination. Standard deviation was 0.0003 g/cm3.
Showing very good correlation of the two determinations.
