A solute diffuses into fresh liquid that may be considered infinite in depth. The mass transfer is governed by Fick's 2nd law and can be regarded as a unidirectional process of diffusivity equal to 0.1 cm2/s. At a certain time into the process, the interface flux is equal to 0.17gmol/m2s and the total amount of solute that has crossed the interface is 3.4gmol/m2. a. 12 points. Calculate the time when that happens. b. 18 points. Calculate the solute concentration and flux at a depth of 2cm and a time of 10s, and explain whether your answers make sense or not (3 points).
