Density = 1.058 g/cm3
Executive summary:

Density of the test substance was measured using helium pycnometry according to ASTM B923 -10 with slight alterations. Specifically, the test sample (< 1 g) was outgassed at room temperature in a vacuum oven for 16 h, weighed before charging to the sample holder and placed in the Micromeritics AccuPyc 1330 instrument. The total sample weight loss after drying was 1.83%. The sample was flushed fifteen times with helium and the volume of the sample measured a total of ten times. The average volume was divided by the measured mass of the sample to determine density. The density was 1.058 g/cm3
