Question
An element (atomic mass 100g/mol) having BCC structure has unit cell edge 400 pm. the density of element is (No. of atoms in BCC, Z = 2).
Options
A.2.144g/cm3
B.7.289 g/cm3
C.5.188 g/cm3
D.10.376 g/cm3
Solution
Mass of two atoms = 
× 2g
=
kg
Volume of cell = (4 × 10-10)3 = 64 × 10-30
Density =
Density =
× 106 kg/m3
=
gm/cc
=
gm/cc = 5.188gm/cc
× 2g=
kgVolume of cell = (4 × 10-10)3 = 64 × 10-30
Density =
Density =
× 106 kg/m3=
gm/cc=
gm/cc = 5.188gm/ccCreate a free account to view solution
