An element has atomic mass 93 "g mol"^(-1) and density 11.5 "g cm"^(-3

1.	An element has atomic mass 93 "g mol"^(-1) and density 11.5 "g cm"^(-3). If the edge length of its unit cell is 300 pm, identify the type of unit cell
Answer» Solution : `rho=(ZxxM)/(a^3xxN_0), Z=(rhoxxa^3xxN_0)/M =((11.5 g CM^(-3))(300xx10^(-10)cm)^3(6.023xx10^23 mol^(-1)))/(93 g mol^(-1))=2.01 approx2` HENCE, the type of unit cell is BCC.
