Please show work neatly thank you!!!

6. Tanks A, B, and C (of volumes VA, VB, and Vc, respectively) containing a salt solution (initial mass concentrations CA,0, CB,0, and cc,0) are connected by pipes in that order. Pure water flows into tank A at a volumetric rate r; liquid flows from A to B, from B to C, and from C to waste at rate r. (a) Using a mass balance for salt on each tank, set up a system of differential equations to describe the salt concentration in each tank (ca(t), co(t), co(t)) as a function of time. Also state the initial conditions needed to find a unique solution. (b) Without solving, predict limiting values of ca(t), co(t), and co(t) as t +
