Copper crystals have fcc unit cells: Calculate the mass of a unit cel – InterviewSolution

1.	Copper crystals have fcc unit cells: Calculate the mass of a unit cell of copper crystal (atomic mass of copper=63.54u)
Answer» Solution :Mass of a unit cell of COPPER crystal = mass of 4 ATOMS of CU = `frac{ZM}{N}` = `frac{4xx63.54}{6.02xx10^23} = 42.21xx10^(-23)= 4.221xx10^(-22)g`
