Method for Determination of

Density of Liquids (First Revision)

 

 

Principle of

Method

Determination of the mass at a

given temperature of a volume of

the material contained in a density

bottle (pyknometer) and

determination of the volume of the

latter by determining the mass of

the corresponding volume of water

at the same temperature. The

density is obtained by dividing the

mass of material by its volume.
