PROBLEM SOLVING: Solve the following problems completely, neatly and orderly. Express all answers to the nearest 4th decimal place. No unit or wrong unit means wrong answer. I. 1. Cobalt crystallizes in a HCP unit cell. Its atomic radius is 0.1253 nm. Its density is 8,900 kg/m?. Using this information, estimate Avogadro's number. 2. A hypothetical alloy has a face-centered cubic unit cell. Its density is 10,470 kg/m³, and its atomic weight is 106.8 g/mole. a) What is the atomic radius of the alloy in cm? b) What is the volume of the single atom of the alloy in cm?
