How can I properly calculate concentration of a chemical (benzene) supplied by diffusion via capillary into a laminar flow of air?

We have air with constant benzene concentration 0.02628 mol/m3 connected via the capillary (0.31 mm i.d., 48 mm length) to the flow path of air flowing at the rate of 100 mL/min (velocity = 2.36...
