How do you calculate the percentage of mass in the solution (aqueous) phase

So I'm having trouble with one of my questions for my hydrology assignment and I would appreciate it a lot if one of you could help me.

 

Consider an aquifer contaminated with an aqueous phase and a sorbed phase. The organic carbon content (foc ) is 0.0025, the porosity is 40%, bulk density is 1.4 g/cm 3 , and log Koc is 2.2. For a unit volume of aquifer, calculate the percentage of mass in the solution (aqueous) phase and the percentage of the mass in the sorbed phase.

 

How would i go about calculating the mass in the solution of the aqueous phase.

I found the Kd by doing Koc=Kd/foc

You need first to calculate the total solids, but I am not clear what the units of your organic carbon content are.

 

Then I suggest you calculate the partition coefficient, Kp whichdivides this up between the phases, following the priocedure in this Environmental Protection Agency (EPA) document
