2. The density of copper is 8.97 g/cm3. What is the volume, in mL, of a 1.00 kilogram mass of pure copper? 3. Why is copper plumbing used in our homes but not aluminum plumbing? 4. The average human needs 2.0 mg of copper ions, Cu2, per day in their diet. This is how many copper ions? 5. Copper is extracted from the ore, chalcopyrite, CuFeS2. How many kilograms of a 0.862% chalcopyrite ore will be necessary to produce 1.00 kg of pure copper? The percentage of copper in chalcopyrite needs to be known to work this problem. 111
