Results and discussion

Density
Key result
Type:
density
Density:
1.08 g/cm³
Temp.:
20 °C
Remarks on result:
other: The difference between the results of the two measurements was < 0.02 g/cm³. According to the guideline, the density of the test item is therefore given as the mean value.

Any other information on results incl. tables

The density (ρ) of a substance is the quotient of its mass and its volume and is expressed in SI units of kg/m3.

The individual measurements were obtained with a deviation of ≤ 0.01 g/cm^3.

The individual density measurements were 1.077 g/cm³ (test 1) and 1.079 g/cm³ (test 2).

Applicant's summary and conclusion

Conclusions:
A pycnometer was used for the determination of the density of JNJ-39005525-AAA (EMME).
The density of the test item at 20ºC was 1.08 g/cm^3 (1.08 x 10^3 kg/m^3).
