The density of the test substance is 1.11g/cm3(1.11 103kg/m3)
Relative Density D204 = 1.11

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 (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 = 9.69 cm3
Exp. 2: D = 9.69 cm3
Mean D = 9.96 cm3
3. Density of test substance = (C- A) / D
Exp. 1: density = 1.11 g/cm3
Exp. 2: density = 1.11 g/cm3
Mean density = 1.11 g/cm3
Description of key information
Density: 1.11 g/cm³ at 20°C.
Key value for chemical safety assessment
Additional information
The density was determined by pycnomoeter method according to OECD Guideline 109.
