3. (a) Calculate the surface area of an atom with a radius of 0.15 nm and a mass of 100 amu"s. (b) In a recent article*, MOFs (metal-organic framework) have been synthesized with surface areas up to 4,500 m2/g. Discuss your calculation from (a) with the results from this article. (c) What type of an isotherm did MOF-177 in the article show?
