The density of the test item Dilanthanum tricarbonate was calculated as
3.4767 ± 0.0012 g/cm3at a temperature range of 18.8 - 20.1 °C.
Precision of the value is given as maximal error of determination.
The standard deviation of the two values is higher than the maximal error, indicating that the error of the duplicate determination was higher than the calculated value for a single determination. The measured values show good correlation (RSD 0.15%), therefore, the study is considered valid.
The temperature during the determination was not constant to ± 0.5 oC. As the test item consists of a solid, the change in density is considered as uncritical.
