Equation 1 (Calculation for the density of water):

Mass of water / volume of pycnometer = Density of water

 

Equation 2 (Calculation for the density of immersion liquid):

 

PIL = (m1/ mW) x PW,t

 

Where:

m1 is the mass of the immersion liquid

mW is the mass of water

PW,t is the density of water at temperature t
