A protein diffuses from left to right through a thick biological membrane (thickness = 10 cm) having a cross-sectional area of 6 cm2. The diffusion coefficient D for this membrane-protein system is 5.0 x 10-10 m2/s. A total mass of 8.0 x 10-14 kg of the protein is transported across the membrane in 15 sec. If the protein density on the left side of the membrane is 3.77 x 10-3 kg/m3, compute the protein density on the right side of...

Oxygen diffuses from the surface of insects to the interior through tiny tubes called tracheae. An average trachea is about 2 mm long and has cross-sectional area of 2 times 10^-9 m^2. Assuming the concentration of oxygen inside is half what it is outside in the atmosphere calculate the diffusion rate J. The diffusion constant is 1.8 times 10^-5m^2/s. Express your answer to two significant figures and include the appropriate units.
