1. A metal A Is diffusing into another pure metal B to form an alloy. After 30 hours, the concentration of A is 3.2wt% at a distance of 1.5mm from the interface between metals A and B. The diffusion coefficient of A in B corresponding to the reaction conditions is 3.84 x 10^-11m²/s. Determine the surface concentration C_s.
