At low temperatures, xenon freezes to a solid having a density of 5.679 g/cm3. Below 84 K, argon also freezes to a solid that has a similar structure but different volume and mass. If the volume of each unit cell in argon is 91 percent of the xenon unit cell, what is the predicted density of solid argon?
