1.	X- ray diffraction studies show that copper crystallizes in an fcc unit cell with cell edge of ` 3.608 xx 10^(-8) ` cm. In a separate experiment, copper is deteremined to have a density of 8.92 g/`cm^(3)` calculate the atomic mass of copper.
Answer» ` P = (Z xx M)/(a^(3) xx N_(0)) or M = ( p xx a^(3) xx N_(0))/Z` for fcc lattice , Z= 4. Hence , ` M = (( 8.92 " g cm" ^(-3)) ( 3.608 xx 10^(-8) cm) ^(3) ( 6.022 xx 10^(23) " atoms mol"^(-1))) = 63.1 " g mol ^(-1)` Atomic mass of copper = `63.1 "g mol"^(-1)`
