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 ?
