1.	An element has atoic mass93 " g mol" ^(-1)and density11.5 " g cm" ^(-3). If the edge length of its unit cell is 300 pm,identify the type of unit cell.
Answer» SOLUTION :`p = (Z xx M)/(a^(3)xxN_(0)) , Z = ( p xx a^(3) xx N_(0))/M = (( 11.5 " g cm"^(-3)) (300xx 10^(-10)"cm")^(3)(6.023 xx10^(23) "mol"^(-1)))/(93" mol"^(-1)) = 2.01 =2 ` Hence, the TYPE of unit cell in BCC.
