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)
d (IL) = (m1 x dW,t)/mW
Where: m1 is the mass of the immersion liquid; mw is the mass of water; dW,t is the desity of water at temperature t
Calculated value for the density of immersion liquid = 964 kg/m3 @ 20°C

Equation 3 (Calculation for the density of the sample)
d S,t = (ms x d (IL))/(m1 - m2)
Where: ms is the mass, in grams, of the sample; m1 is the mass, in grams, of immersion liquid required to fill empty pycnometer; m2 is the mass, in grams of immersion liquid added to fill pycnometer containing the sample; d (IL) is the denisty of the immersion liquid (as determined by equation 2).
Description of key information
The density and relative density of the test item were found to be 1.190 g/cm^3 and 1.190 respectively according to guidelines.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.19
