Biology

Insects obtain oxygen by diffusion through tracheae, tinytubes connecting the outside air to the interior of the body. Atypical such tube is about 2.3 mm long and has cross-sectional areaof 2.2 × 10-9 m2. Assuming the concentration of oxygen inside is 48% what it is outside in the atmosphere,

a. find the concentration of oxygen in the air at 24.9 ° C.Assume 21% is oxygen and the pressure is 1 atm.
--> using ideal gas law, a.) = 8.587 mol/m^3


b. Calculate the diffusion rate J of oxygen molecules in unitsof kg/s. Take the diffusion constant to be 1 × 10-5m2/s.

*Diffusion constant is 1*10^-5
