Sucrose is allowed to diffuse along a 8.0-cm length of tubing filled with water. The tube is 6.1 cm2 in cross-sectional area. The diffusion coefficient is equal to 5.0 10-10 m2/s, and 8.0 10-14 kg is transported along the tube in 18 s. What is the difference in the concentration levels of sucrose at the two ends of the tube?
Answer in kg/m3
