4) Fe-C has a background concentration of 0.20 wt% carbon and is heated to 1250 K. The carbon leaves the Fe and therefore has a 0 wt% carbon at the surface, and therefore the partial pressure of C at the surface can be assumed to be zero. After 8 hours, how far from the surface will the concentration of carbon be 0.15 wt% ? Use the value of the diffusion coefficient of 7x10-11 m²/s.
