Gold (atomic radius=0.144nm) crystallises in a face-centred unit cell what is the length of a side of the cell?

In a face centred cubic unit cell what is the volume occupied?

Define the following terms : Face centred unit cell

A metal crystallizes in a face centred cubic unit cell with a=0.560nm. Calculate the density of the metal if contains 0.1% Schottky defects. (Atomic mass of metal = 40 g mol^-1 ).

The total number of tetrahedral voids in the face centred unit cell is

Density of a unit cell is respresented as rho = (" Effective no. of atoms (s)" xx "Mass of a unit cell ")/("Volume of a unit cell ")=(Z.M)/(N_(A).a^(3)) where , mass of unit cell =mass of effectuive no . of atoms(s) or ion (s). M= At . mass// formula N_(A) = Avogadro' s no . rArr 6.0323 xx 10^(23) a= edge lemght of unit cell Silver crystallizes in a fcc lattice and has a density of 10.6 g//cm^(3) . What is the length of a edge of the unit cell ?

CsCl has body centred cubic lattice with the lengh of a side of a unit cell 412.1 pm and aluminium is face centred cubic lattice with length of the side of unit cell 405 pm. Which of the two larger density? (Atomic mass of Cs=132.9, Cl=29.9).

If an element (at. Mass =50) crystallises in fcc lattie ,with a= 0.50 nm . What is the density of unit cell if it contains 0.25% Schottky defects (use N_(A) = 6xx 10^(23) )?
