2. In a gas-phase diffusion mass-transfer process, the steady-state flux of nitrogen gas, N2, in a binary mixture of nitrogen and Argon, Ar, is 6.51010kgmole/cm2s, and the flux of argon is 0 . At a particular point in the diffusion space, the concentration of nitrogen is 3.21103kgmole/m3 and the concentration of argon is 2.56102kgmole/m3. Estimate the individual net velocities of nitrogen and argon along the direction of mass transfer, the average molar velocity, and the average mass velocity
