Key result

Type:

relative density

Density:

1.38 g/cm³

Temp.:

20 °C

Individual Measurement:

	Experiment 1	Experiment 2
Density of Water at 20°C g/mL (X)	0.99821	0.99821
Weight of Pycnometer g (A)	20.5949	22.7487
Weight of Pycnometer g (A1)	20.5948	22.7487
Weight of Pycnometer + Water g (B)	45.1158	47.6114
Weight of Pycnometer + Test Item g (C)	54.4899	57.1173

Calculations for the Determination of Relative Density:

Density of water at 4°C = 1g/mL (Y)

1. Volume of pyncometer (mL) V= (B-A)

X

2. Density of test substance (g/mL) D1 =(C-A1)

V

Relative density = D1

Y

Using the values and the equations above, the relative density of the test item was calculated.

	Experiment 1	Experiment 2	Average D1
Volume of Pycnometer mL (V)	24.5649	24.9073
Density of test substance g/mL (D1)	1.3798	1.3799	Rounded to 4 significant figures 1.3799
Mean Relative Densuty	1.38 (rounded)

Conclusions:

The relative density of the test item has been determined to be 1.38 ± 0.01°C at 20.0°C ±0.5°C

Key value for chemical safety assessment

Relative density at 20C:

1.38
