Table 1. Determining the Density of the Immerision Liquid
| Run Number | 1 |
| Mass of Empty Pycnometer (g) | 21.0 |
| Temperature (°C) | 20 |
| Mass of water added to Pycnometer (g) | 24.6 |
| Mass of immersion liquid added to Pycnometer (g) | 23.9 |
| Volume of Pycnometer (ml) | 25.0 |
| Calculated Density of water using Equation 1 (g.cm-3) | 0.99 |
| Calculated Density of immersion liquid using Equation 2 (g.cm-3) | 0.96 |
| Density of immersion liquid (kg.m-3) | 960 |
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 = mIL x ρW,t.( mW)-1
Where :
mIL is 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 = 960 kg.m-3 @ 20°C
Table 2. Determining the Density of the Sample
| Run Number | 1 | 2 |
| Mass of Empty Pycnometer (g) | 21.0 | 21.0 |
| Mass of sample added to empty Pycnometer (g) | 13.0 | 11.0 |
| Mass of immersion liquid added to Pycnometer (g) | 16.4 | 17.3 |
| Mass of immersion liquid and sample (g) | 29.4 | 28.3 |
| Calculated Density of Sample(g/cm3) | 1.66 | 1.58 |
| Density of Sample (kg/m3) | 1660 | 1580 |
Equation 3 (Calculation for the density of the sample)
ρs,t =msρIL .(m1– m2)-1
Where: ms is the mass, in grams, of the sample; m1 is the mass, in grams, of immersion liquid required to fill the pycnometer; m2 is the mass, in grams of immersion liquid required to fill the pycnometer containing the specimen; ρIL is the density of the immersion liquid. Mean Result : 1619 kg.m-3 at 20°CDescription of key information
The determination was carried out in a GLP laboratory using a pycnometer method according to Method A3 Relative Density in Comission Regulation (EC) No 440/2008. The density was determined to be 1619 kg/m3.
Key value for chemical safety assessment
- Relative density at 20C:
- 1 619
