Density:

Temp.:
21 °C

Five repeat measurements of helium gas expansion were performed to evaluate the volume occupied by the sample. The volume was evaluated to be 0.3210 cm3. Since the sample weight used was 0.4867 grams, the density was evaluated to be 1.5164 g/cm3. The helium pycnometry measurement reflects the density of the solid portion of the material excluding the pores and therefore has units of grams of solid per volume of solid assuming no closed porosity. As such, it is equal to the skeletal density of the material.

Conclusions:
The density of 2-hydroxyethyliminodi(acetic acid) was determined to be 1.5164 g/cm3 by the heelium pycnometr method.
Executive summary:

The density of 2-hydroxyethyliminodi(acetic acid) was determined to be  1.5164 g/cm3 by the heelium pycnometr method.
