Applicant's summary and conclusion

Conclusions:

Using the pycnometer method, a density of

2.0091± 0.0014 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 0.0035 g/cm3, showing good correlation of the two determinations.
