Remarks on result:
other: relative density D20/4 = 4.74

In order to calculate sample relative density D204, the value of the density of water at 4 °C was looked up in the literature, this being 0.999975g/cm³ according to the handbook of Chemistry and Physics. If it is assumed that sample density at 20 °C does not differ more than the own measurement error, this value is calculated from the quotient between the value of sample density at 20 °C and the value of water density at 4 °C, both expressed in the same units.

Conclusions:
The relative density D20/4 of the sample is 4.74.

Description of key information
