During dialysis, a patient's blood is removed and pumped through a membrane where toxins are removed. If we wish to reduce the concentration of the toxins by 90.%, calculate the time required for dialysis (hours). Assume that blood is removed and pumped through the membrane at 1.0L/min, a person's blood volume is 4.5L, and that toxins are initially at a concentration of 50.0mM. Model the rate at which toxin is removed by the membrane as: Toxinremoval(minmol)=0.05CtoxinVpump Where Ctoxin is the concentration of toxin in the blood (mol/L) and Vpump is the volumetric flow rate of blood pumped to the dialysis membrane (L/min). Repeat problem 2. but now consider that the person's body is generating toxin at a rate of 0.10mmol/min, even during dialysis
