Calculation of the relative density

Relative Density (D25/25) = 1.08019 g/cm³/ 0.99704 g/cm³= 1.0834

Conclusions:

The substance is slightly denser than water.

Executive summary:

The relative density of the test substance was using oscillating densitimeter method. After calibration using air and water, a sample was measured in triplicate at 25 °C, and the mean relative density was calculated towards water at 25°C.

The relative density (D25/25) of the test substance has been determined to be 1.0834.
