 Executive summary:
Using the pycnometer method, a density of 1.9896 ±0.0015 g/cm³ at 20.0 ±0.4 °C was measured. This value is the mean of two independent determinations with the maximum error of a single determination. Standard deviation was 0.0001 g/cm³, showing very good correlation of the two determinations. Thus, the experiment was considered valid.

Calculation of Results
Density of Test Item
The Density ρ of the test item was calculated as follows:
ρs _= ((m4m1))/((m3m1 )(m5m4))*ρ_(repl.)
with
ρs = density of solid test item in g/cm³
m1 = mass of empty pycnometer in g
m3 = mass of pycnometer with replacement liquid in g
m4 = mass of pycnometer with solid test item in g
m5 = mass of pycnometer with replacement liquid and test item in g
ρrepl. = density of replacement liquid in g/cm³
The relative density of the test item has the same number value, but no unit, assuming that relative density is given as the ratio of test item density to density of water at 4 °C, having a standard density of 0.999975 g/cm³ (source: CRC Handbook of Chemistry and Physics  90th edition / Section 6  Fluid properties  p.6  7).
The density of the replacement liquid is: ρrepl. = (m3m1)/(m2m1 )*ρH2O
with
ρrepl. = density of replacement liquid in g/cm³
m1 = mass of empty pycnometer in g
m2 = mass of pycnometer with water in g
m3 = mass of pycnometer with replacement liquid in g
ρH2O = density of water at test temperature (0.9982 g/cm³ at 20.0 °C)
Density of water was determined at 20.2 °C as 0.9981652 g/cm³ (N.B. Vargaftik, et al., International tables of the surface tension of water, J .Phys.Chem.Ref. Data, 12,817,1983)
Calculation of Error
The relative error of the method was calculated from:
Δρ = 2* Δm*100%/m4m1 + 4* Δm*100%/(m3m1)(m5m4) + 2* Δm*100%/m3m1 + 2* Δm*100%/m2m1
with
Δρ = relative error of the measured density
Δm = absolute error of single weighing (0.0003 g)
Calculation of Relative Standard Deviation RSD was done as follows: RSD = sd*100/density(mean)
with
RSD = Relative Standard Deviation in %
sd = Standard Deviation in g/cm³
The following values were calculated.

Note: All calculations are performed with unrounded values. Therefore, recalculation with rounded values may lead to slightly different results.
The density of the test item AM(pfa)4 was calculated as 1.9896 ±0.0015 g/cm³ at 20.0 ±0.4 °C, which is the mean of two values. Precision of the value is given as maximal error of a single determination. The standard deviation of the two values is much lower than the maximal error of a single determination, indicating that the error of the determination was lower than the calculated value. Correspondence of the values is very good. Therefore, the study is considered valid.
