11 Uncertainty of Measurement for Density Determination of Solids
This table shows the approximate readability of the balance in connection with the
density kit. Observe that these values have only been determined by calculation and
that influent parameters such as described in chapter 6 have not been taken into
consideration.

*when using a balance with a readability of 0.1 g, the numbers in this table have to be
multiplied with 10. When using a balance with a readability of 0.001 g, divide the numbers
through 10.
Reading example for table:
In a balance with a resolution of 0.001 g and a sample with a weight of 10 g, whose
3
density is 5 g/cm
, the display graduation is at 0.007 g/cm
