"If I am measuring water density (mass of water /(volume of the system
-volume of silicon nitride)), then it gives 1 g/cm^3"
This sounds like the correct way to calculate the density of water. And you
get the correct answer. I'm not sure what the problem is.
Silicon nitride has a higher mass density than water (
https://en.wikipedia.org/wiki/Silicon_nitride ), so if you include it in
the calculation you will get a density in between the density of water and
the density of silicon nitride.
