Calculations:

Absolute density of a substance (δ) is calculated as: δsubs= WS / Vsubs= WS / (Vpyc– Vhex) = WS / (Vpyc– WH2/δHex) = WS / (Vpyc– WH2* Vpyc/ WH1)

 Relative density (δ204) is calculated as: δsubs/ 0.999973

Conclusions:
The relative density of the test substance is 1.798 at 20 °C
Executive summary:

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.

Relative density of the substance is 1.798 at 20 °C

Description of key information

Relative density = 1.798 at 20 °C

Key value for chemical safety assessment

Relative density at 20C:
1.798

Additional information

Relative density of the substance is 1.798 at 20 °C as determined by the pycnometer method
