- SOP Reference: CTL SOP No. 403

- Apparatus: Pycnometer of known volume, chemical balance.


Determining the Density of the Sample:

Run Number                                                            1              2

Volume of Pycnometer (ml)                                    24.4         24.4

Mass of empty Pycnometer (g)                              20.15       20.15

Mass of sample & Pycnometer (g)                        40.52       40.63

Mass of sample added to empty Pycnometer (g) 20.37       20.48

Calculated density of sample (                   0.834       0.839

Density of sample (kg.m-3)                                      834          839

Mean Result (kg.m-3)                                                      836

Mean Result:

Relative density (D204): 0.836

Sample density: 836 kg.m-3@ 20°C

Note: The pycnometer method was applied due to limited sample being available for the hydrometer method.

Relative density: 0.836
