In a gas-phase diffusion mass-transfer process, the steadystate flux of species A in a binary mixture of A and B is 5.0105kgmoleA/m2s, and the flux of B is 0 (zero). At a particular point in the diffusion space, the concentration of species A is 0.005kgmole/m3 and the concentration of species B is 0.036kgmole/m3. Estimate the individual net velocities of species A and B along the direction of mass transfer, and the average molar velocity
