Density = (ms x density IL ) / (m1 – m2)

Where: ms is the mass, in grams, of the sample;

m1 is the mass, in grams, of immersion liquid required to fill the empty pycnometer;

m2 is the mass, in grams of immersion liquid added to fill the pycnometer containing the sample;

densityIL is the density of the immersion liquid

Mean Result : Relative density (D20 4) = 1.009

Sample density = 1009 kg.m-3 @ 20°C

Description of key information
