It has a mass of 9.47 g when measured in water. Answer these four questions: What is the density of the sample? How many atoms are in the sample? What is the simple volume of the space including and surrounding each atom? Assume the atoms are evenly distributed throughout the sample. That is no FCC, BCC, or HCP crystal structure. What is the diameter of each atom?
