Calculate the concentration (in moles/m^3) of oxygen in air (21%oxygen) assuming it acts as an ideal gas at 21oC. Oxygen diffusesto the inside of insects through tiny tubes called tracheae whichverage 2mm long and 2x10^-9 m^2 in cross-section. Estimate theaverage diffusion rate assuming the concentration of oxygen insideapproaches 0. Estimate the average time it takes for a molecule todiffuse in. What is the average speed for such a molecule. What is the rms speed for such a molecule?
