Answer:
The unit cell edge lenght in pm is equal to 361 pm
Explanation:
Data provided:
ρ=Copper density=8.96 g/cm3
Atomic mass of copper=63.54 g/mol
Atoms/cell=4 atoms (in theory)
Avogadro's number=6.02x atoms/mol
Since copper has a cubic structure, its cell volume is equal to , which can be obtained through the relationship:
cell volume=
Substituting the values:
cell volume=
clearing, we have:
a=
We convert from centimeter to picometer, 1cm=1xpm
a=
