Calculations:
A = weight of empty pycnometer (g)
B = weight of the pycnometer with Milli-Q water (g)
C = weight of the pycnometer with the test substance (g)
D = volume of the pycnometer (g/cm3)
SMW = density of water at the test temperature (g/cm3) (CRC Handbook of Chemistry and Physics, 1981)
1. SMW (resulting from the test temperature) = 0.9982 g/cm3
2. Volume of pycnometer = D = (B - A) / SMW
Exp. 1: D = 9.7312 cm3
Exp. 2: D = 9.7259 cm3
Mean D = 9.729 cm3
3. Density of test substance = (C - Amean) / Dmean
Exp. 1: density = 1.127 g/cm3
Exp. 2: density = 1.126 g/cm3
Mean density = 1.13 g/cm3
Description of key information
Density 1.13 g/cm³ at 20°C
Key value for chemical safety assessment
Additional information
A density value of 1.13 g/cm³ at 20°C was determined by pycnometer method according to OECD Guideline 109. This is supported by a value of 1.11 g/cm³ at 20°C determined by another density study according to OECD Guideline 109. The supporting result is in good agreement with the key study.
