🤓 Based on our data, we think this question is relevant for Professor Staff's class at TCU.
We are going to need to calculate the density assuming both structure types. We then compare the densities to the given values to know the appropriate structure.
Before anything else, convert the radius pm to cm to be consistent with the units in the density.
The radius of gold is 144 pm, and the density is 19.32 g/cm3. Does elemental gold have a face-centered cubic structure or a body-centered cubic structure?
