2. A sedimentary rock consists of uniform size hematite (Fe2O3) and magnetite (Fe304) particles. If the diameters of hematite and magnetite particles are 2 and 5 microns, respectively, and the wt% of hematite is 50%, what is the specific surface area of this material in m2/gm. What is the volume percentage of the hematite and magnetite? What weight of copper, in lbs, would be required to coat the entire surface of one ton of the particles with a monolayer of cupric ions? Given: Q=2.0, Fe2O3=5.26 gm/cm3, p. Fe30455.0 gm/cm3, cross-section of Cu++=16 A2
