A conical flask with a porous stopper is used to cultivate broth containing 8.1 g of moist microorganisms and 98 mL of aqueous solution at 39 degrees Celsius. During the fermentation process, the use of a porous cork allows air to enter the flask. The solubility and diffusivity of oxygen gas in water at 39 degrees Celsius are calculated to be 3.1 x 10-4 kg mol oxygen / m3 and 4.1 x 10-9 m2/s, respectively. Calculate the maximal rate of mass transfer of oxygen to the surface of the microorganism if the solution is saturated with air at atmospheric pressure.
