Iridium (Ir) has a face-centered cubic unit cell with an edge length of 383.3 pm. The density of iridium is 22.61 g/cm3. Use these data to calculate a value for Avogadro's 5. number. The unit cell for an oxide of an unknown metal A is shown below. The oxygen atoms are all in the fcc positions. The metal ions are all in the tetrahedral sites (holes). What is the formula of this compound? What is the charge of the metal ions in this compound? 6.
