Answer:
![X_B = 1.8 \times 10^{-3} m = 1.8 mm](https://tex.z-dn.net/?f=X_B%20%3D%201.8%20%5Ctimes%2010%5E%7B-3%7D%20m%20%3D%201.8%20mm)
Explanation:
Given data:
Diffusion constant for nitrogen is ![= 1.85\times 10^{-10} m^2/s](https://tex.z-dn.net/?f=%3D%201.85%5Ctimes%2010%5E%7B-10%7D%20m%5E2%2Fs)
Diffusion flux ![= 1.0\times 10^{-7} kg/m^2-s](https://tex.z-dn.net/?f=%3D%201.0%5Ctimes%2010%5E%7B-7%7D%20kg%2Fm%5E2-s)
concentration of nitrogen at high presuure = 2 kg/m^3
location on which nitrogen concentration is 0.5 kg/m^3 ......?
from fick's first law
![J = D \frac{C_A C_B}{X_A X_B}](https://tex.z-dn.net/?f=J%20%3D%20D%20%5Cfrac%7BC_A%20C_B%7D%7BX_A%20X_B%7D)
Take C_A as point on which nitrogen concentration is 2 kg/m^3
![x_B = X_A + D\frac{C_A -C_B}{J}](https://tex.z-dn.net/?f=x_B%20%3D%20X_A%20%2B%20D%5Cfrac%7BC_A%20-C_B%7D%7BJ%7D)
Assume X_A is zero at the surface
![X_B = 0 + ( 12\times 10^{-11} ) \frac{2-0.5}{1\times 10^{-7}}](https://tex.z-dn.net/?f=X_B%20%3D%200%20%2B%20%28%2012%5Ctimes%2010%5E%7B-11%7D%20%29%20%5Cfrac%7B2-0.5%7D%7B1%5Ctimes%2010%5E%7B-7%7D%7D)
![X_B = 1.8 \times 10^{-3} m = 1.8 mm](https://tex.z-dn.net/?f=X_B%20%3D%201.8%20%5Ctimes%2010%5E%7B-3%7D%20m%20%3D%201.8%20mm)
