Density:

4.475 g/cm³

Temp.:

20 °C

Remarks on result:

other: standard deviation: 0.04 g/cm³; no temperature was stated, 20 °C were assumed; relative density: 4.475

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 0.999975 g/cm³ according to the Handbook of Chemistry and Physics; David R. Lide; Editor in Chief. 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 density of magnesium ferrite was determined to be 4.475 g/cm³. The relative density at 20 °C compared to water at 4 °C was calculated to be 4.475.
