In the old definition of standard state, STP corresponded to conditions of "standard" temperature (T=0°C) and standard pressure (p= 1 atm).
You are given a small bar of an unknown metal X. You find the density of the metal is 10.5 g/cm^3. Another experiment tells you the edge-length of the face centered cubic unit cell of this metal has a length of 4.09 x 10^-10 m. What is the density
