Diffusive flux & dimensional analysis. A spherical tumor with a radius of 2 mm is generating 50 nanomoles of a chemoattractant molecule per minute. Assume there is no reactive loss of the molecule and it all diffuses from the tumor surface into the surrounding tissue.

a. What is the surface flux generated in units of mmol/m2min?

b. What is the total quantity of chemoattractant generated in one day in moles?
