🤓 Based on our data, we think this question is relevant for Professor Staff's class at TCU.

FREE Expert Solution

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.
