Problem in defining molar fraction (mole/mole) in "Transport of diluted species in porous media"

Hi all
I am using "Transport of diluted species in porous media" and "Darcy Law" for a flow of a solution containing a mixture of iron nanoparticle and polymer in water. Nanopartilce and polymer are my two species. The mixed solution should flow from an injection well into the groundwater. Right now the solution is flowing from the injection well radially.
But, I have to consdier polymer density. I have follwing equation for density calcuation. log(vis_sol) = xpoly* log(vis_poly) + xnano* log(vis_nano) + log(vis_water)
vis_sol= solution viscosity, vis_poly=polymer viscosity, vis_nano=nano partcile viscosity, vis_water= water viscosity, xpoly = mole of polymer/mole of water [molar fraction] xnano=mole of nanoprtcile/mole of water [molar fraction]
The main problem is I can not define this equation in variable section because my model takes the polymer and nanoprtcile as molar flux (mol/m.s) but not molar fraction. So the equation is not working.
Any idea to solve this problem or how I can define molar fraction in 'transport of diluted species"?? I will be grateful if anyone can help me out of this problem.
Thanks! Asad
