A sedimentary rock consists of uniform size silica (SiO{2}) and corundum (Al{2} O3}) particles, both with If the diameters of silica and corundum particles are 2 and 5 microns respectively , and the wt of silica is 50% what is the specific surface area of this material in m ^ 2 / g m . What is the volume percentage of the silica and corundum? 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 (Cu^ ++ ) ions?

3. A sedimentary rock consists of uniform size silica (SiO2) and corundum (A1203) particles, both with v=1.75. If the diameters of silica and corundum particles are 2 and 5 microns respectively, and the wt% of silica is 50%, what is the specific surface area of this material in m2/gm. What is the volume percentage of the silica and corundum? 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 (Cu) ions? Given: v=1.75, PS102=2.65 gm/cm3, PA1203=4.0 gm/cm3, cross-section of Cu++-16 A2, 1 ton-2000 lbs, 1 lb = 454 gm
