* We have data of density binary solvent mixture at different molar fraction (x1, x2)
* We add a mass (m1) of nanofluid with known density ( rho1) into a mass (m2) of binary mixture with known density ( rho2) and molar fraction (x1).
* Please what formula used to calculate the volume fraction of this nanofluids

Slurry density formulas, yet intended for either powder suspensions or colloidal solid-liquid dispersions ― where volume additivity can usually be expected to approximately hold ― were presented elsewhere at this forum:

Nonetheless, for nanofluids, the excess volume of mixing can typically be expected to play a fairly significant role.
