After removing certain quantity of water, the concentrated polymer solution is treated with hydrogen gas stored at 358K in 3.0 m internal diameter, 5cm thick spherical container made of nickel. Molar concentration of hydrogen in Ni at the inner surface is 0.09 kg mole/m³ and is equal to zero at outer surface. Mass diffusivity of hydrogen into Ni, D=1.2 x10-12 m/s Determine the molar diffusion rate of hydrogen through the walls of the container
