Applicant's summary and conclusion

Conclusions:
Vinyltrimethylsilane density = 0.688g/mL ± 0.002 at 20.0˚C
Executive summary:

The density of vinyltrimethylsilane was determined using a calibrated 50mL volumetric flask and a calibrated Mettler Toledo XP105 balance.

The flask was calibrated per ASTM method E542-01 using water at 20.0˚C. The resulting density for water was within 0.2% of the literature value thus showing that the flask was accurate within ± 0.2% or 0.1mL.

The calibrated flask was dried, filled with high purity vinyltrimethylsilane (Lot# M3M01DMV, 99.58% pure) and weighed in a manner similar to the method used for volumetric calibration. The flask was weighed until three equal, consecutive measurements were found. The sample was then weighed five times and the resulting masses were averaged to determine the final, average fill mass. The average fill mass and calibrated volume were used to calculate the density.

The result of the determination was a density of 0.688g/mL ± 0.002 at 20.0˚C for Vinyltrimethylsilane.
