The density of silver at room temperature is 10.49 g/cm3 . You need to know the density of solid silver just below the melting temperature. At 960°C the lattice parameter was measured to be 0.4176 nm. Compare the theoretical density of silver at 960°C to that at room temperature.

What will be an ideal response?


The theoretical density can be calculated from the weight of silver atoms in a single unit cell divided by the volume of a unit cell. Silver is FCC therefore there are 4 atoms per unit cell. The number of atoms per unit volume is:
