Consider a rectangular-shaped gel tablet of thickness 0.652 cm and width 1.0 cm loaded with the drug Dramamine. The edges of the gel tablet are sealed so that diffusion of Dramamine occurs only along the thickness of the gel tablet. The initial concentration of the drug Dramamine (solute A) in the gel (B) is 64.0 mg/cm³, to provide a total drug dosage of 41.7 mg. The concentration of the drug at the exposed surface of the tablet is maintained at zero to provide a constant sink for mass transfer. The diffusion coefficient of the drug in the gel is 3.0 × 10 cm²/s. What is the residual concentration of drug in the center of the tablet after 96 hours? Compare results using (a) the concentration-time charts and (b) the infinite series analytical solution.
