 Presentation of Results

Results of the single determinations with the respective error as well as the mean value and its standard deviation are presented in the following tables:

   Results of Single Determinations

Determination	Density in g/cm^3	Error of Determ. in g/cm^3
1	0.9926	0.0000
2	0.9926	0.0000

 

  Results – Mean Values

Parameter	Value	Unit	Standard Deviation	Relative Standard Deviation
Volume of Pycnometer	25.07	cm^3	0.0000	0.00%
Density of Test Item	0.9926	g/cm^3	0.0000	0.00%
Density of Test Item	992.6	kg/m^3	0.0	0.00%
Relative Density of Test Item	0.9926		0.0000	0.00%

Note: All calculations are performed with unrounded values. Therefore, re-calculation with rounded values may lead to slightly different results.

 

Conclusions:

The density of the test item 7-(4-ethyl-1-methyloctyl)quinolin-8-ol was calculated as 0.9926 ± 0.0000 g/cm3 at 20.0 ± 0.2 °C.
This value is the mean of two independent determinations ± the standard deviation. Standard deviation shows perfect correlation of the two determinations.
Therefore, the study is considered valid.
 

Executive summary:

Findings and Results:

 

Using the pycnometer method, a density of

 

                                                        0.9926 ± 0.0000 g/cm³at 20.0 ± 0.2 °C

 

was measured. This value is the mean of two independent determinations ± the standard deviation. Standard deviation shows perfect correlation of the two determinations.
