64-2. Diffusion of Sucrose in Gelatin. A layer of gelatin in water 5 mm thick containing 5.1 wt% gelatin at 293 K separates two solutions of sucrose. The concentration of su- crose in the solution at one surface of the gelatin is constant at 2.0 g sucrose/100 ml. solution, and 0.2 g/100 mL at the other surface. Calculate the flux of sucrose in kg sucrose/s-m through the gel at steady state.
