)nitrogen from a gaseous phase is to be diffused into pure iron at 700°c. if the surface concentration is maintained at 0.12 wt% n, what will be the concentration (in weight percent) 4.5 mm from the surface after 8.0 h? the diffusion coefficient for nitrogen in iron at 700°c is 4.6 × 10-10 m2/s.

yes it is balanced
