A biomaterial scaffold matrix saturated with 0.5 moles/cm3 of solute is abruptly brought into contact with a large body of solvent. Assume that the diffusion coefficient of the solute is 10-6 cm2/s. a. How rapidly will a solute diffuse 10 mm from the matrix after 6 hours? (10 pts) b. If the solvent container has a length of 0.1m and negligible width, how much time is the concentration of the solute in the container in a fluctuating state? (10 pts)
