Density = (mass of sample x density of immersion liquid) / (mass of immersion liquid required to fill the empty pycnometer x mass of immersion liquid added to fill the pycnometer containing sample)

Mean result: 1304 kg.m-3 @ 20 degrees C

Conclusions:
The average density for the two results obtained for the 1,1"-isopropylidenediferrocene was determined to be 1304 kg/m3 @ 20°C
Executive summary:

The relative density of 1,1"-isopropylidenediferrocene was investigated in a study using the pycnometer method . This study is assigned a reliability score of 1 in accordance with the criteria for assessing data quality set forth by Klimisch et al (1997).

The testing was performed in duplicate and the average density was determined to be 1304 kg/m3.
