Sucrose is allowed to diffuse along 8.0 cm length of tubing filled with water. The tube is 5.6 cm^2 in cross-sectional area. The diffusion coefficient is equal to 5.0*10^-10 m^2/s, and 8.0* 10^-14 kg is transported along the tube in 19 s. What is the diffrence in the concentration levels of sucorse at the two ends
