Concentration Profile and Flux of a Drug Between two Planes

Question: Suppose a drug is encapsulated between 2 planes at x=0 and x=h. The drug diffuses out of both planes at a constant rate R, so the diffusion equation is,

Calculate the concentration profile inside the planes assuming the boundary conditions c(0)=c(h)=0. In this case, calculate also the total flux out of two planes.
