Can you solve this mass transfer question?

7.2 Typical values of the volumetric mass transfer coefficients for the gas and liquid phases in a wellagitated aerated system (a fermentor or activated sludge reactor) are as follows: gas phase: kdaa=3.9105[g = dry weight) of microbial cells, which may be assumed to be spheres 2m in diameter containing 80% water and having a density of 1.03gcm3. Mass transfer to cells may be assumed to be equivalent to mass transfer between spheres and stagnant fluid. Pressure is 1 atm. For oxygen transfer between the gas phase and the cells, use for oxygen a Henry's constant of 106cm3atm g-mol mo1 and DOW=2105cm2s1. Using Equation 7-43, calculate for this system the overall liquid-phase volumetric mass transfer coefficient [s1] and the fraction of total mass transfer resistance attributable to each of the three mass transfer regimes
