Absolute density of a substance (δ) is calculated as:

δ subs = WS / V subs = WS / (V pyc – V hex ) = WS / (V pyc – WH2 / δ Hex ) = WS / (V pyc – WH 2 * V pyc / WH1 )

Relative density (D²⁰₄) is calculated as: δ subs / 0.999973

Conclusions:

Relative density: 1.399 at 20 °C

Executive summary:

Method

Relative density was determined by means of a pycnometer as per recommendations of OECD 109. Density was calculated from the difference in weight between the full and empty pycnometer and its volume.

Result

Relative density: 1.399 at 20 °C

Description of key information

Relative density: 1.399
