Table 7.1

Measurement	Determination
	1	2
Mass of pycnometer (g)	17.3315	16.8704
Mass of pycnometer and distilled water at 20.0ºC (g)	27.5089	27.2088
Mass of pycnometer and test item at 20.0ºC (g)	27.6178	27.3150
Density of water at 20.0ºC (kg/m^3)	998.20	998.20
Density (kg/m^3)	1.009 x 10^3	1.009 x 10^3
Relative density	1.01	1.01

Mean relative density:        1.01
Temperature:                       20.0 ± 0.5ºC

Conclusions:

The relative density of the test item has been determined to be 1.01 at 20.0 ± 0.5°C.
