2. Pressurized hydrogen gas is stored at 358 K in a 4.8 m outer diameter spherical container make of nickel. The shell of the container is 6 cm thick. The molar concentration of hydrogen in the nickel at the inner surface is determined to be 0.087 kmol/m3. The concentration of hydrogen in the nickel at the outer surface is negligible.
