Results

  Determination 
1 2
a Mass of pycnometer (g) 26.1900 26.1815
b Mass of pycnometer and distilled water at 20 deg C (g) 75.9970 75.9955
c Mass of pycnometer and test material at 20 deg C (g) 66.1627 66.2298
d Density of water at 20 deg C (kg/m3) 998.23 998.23

Mean density of test material = 801.83 kg/m3

Density of water at 4 deg C = 1000.0 kg/m3

Relative density of Alkane 2 = 801.83 / 1000.0

= 0.80183.

The density was calculated using the following formula:

Density = d x (c-a) / (b - a) kg/m3

where:

a = mass of pycnometer (g)

b = mass of pycnometer and distilled water (g)

c = mass of pycnometer and test material (g)

d = density of water (kg/m3)

Applicant's summary and conclusion

Conclusions:
The relative density of Alkane 2 has been determined to be 0.80183 at 20 +/- deg C.
Executive summary:

The experimental procedure used complied with that specified in Method A3 of Commission Directive 92/69/EEC (which constitues Annex V of Council Directive 67/548/EEC).

The relative density of Alkane 2 has been determined to be 0.80183 at 20 +/- deg C.
