Determining the Density of the Immersion Liquid

 

Mass of Empty Pycnometer (g)

24.07

Mass water & Pycnometer (g)

49.34

Mass of IL & Pycnometer (g)

49.34

Calculated Density of IL (g/cm3)

0.998

Volume of Pycnometer (ml)

25.3

Density of Water (g/cm3) ρw,t

0.998

Mass IL in Pycnometer (g) (m1)

25.27

Density of IL (kg/m3)

998

 

Equation 1 (Calculation for the density of water)

Mass of water / volume of pycnometer = Density of water

 

Equation 2 (Calculation for the density of immersion liquid)

 

ρIL = (m1x ρw,t)/mW

 

Where : m1is the mass of the immersion liquid

mW is the mass of water

ρw,t is the density of water at temperature t

 

Calculated value for the density of immersion liquid = 998 kg.m-3@ 20°C

Mean Result (kg.m-3)

1066

 

Equation 3 (Calculation for the density of the sample)

 

ρS,t = (ms xρIL) / ( m1 – m2)

 

Where:

ms is the mass, in grams, of the sample;

m1 is the mass, in grams, of immersion liquid required to fill the empty pycnometer;

m2 is the mass, in grams of immersion liquid added to fill the pycnometer containing the sample;

ρIL is the density of the immersion liquid (as determined by equation 2)

Mean Result :

Relative density: 1.066

Sample density 1066 kg.m-3 @ 20°C

Conclusions:
The relative density of the test substance at 20°C was determined to be 1.066 by pycnometer.
Executive summary:

The relative density of the test substance was determined using pycnometer according to the procedure described in EU Regulation (EC) 440/2008, Annex Part A test A3 and OECD Test Guideline 109. The mean of 2 tests was 1.066.

Description of key information

The relative density of the test substance was determined using pycnometer according to the procedure described in EU Regulation (EC) 440/2008, Annex Part A test A3 and OECD Test Guideline 109. The mean of 2 tests was 1.066.

Key value for chemical safety assessment

Relative density at 20C:
1.066
