The mean density of the sample was determined as 0.405 g/cm³ at 20 °C.

Accuracy and precision – The mass of the sample was measured to an accuracy of ± 0.01 g

The volume of the sample was measured to an accuracy of ± 0.1 cm³.

The estimated accuracy of the method is +/- 0.1 g/cm³.

Conclusions:
According to OECD guideline 109, the tap density of zinc m-toluate is 0.405 +/- 0.1 g/cm³ at 20 °C.
