An element crystallises into a structure which may be described by a cubic unit cell having one atom at each corner of the cube and two atoms on one of its diagonals. If the volume of this unit cell is 24×10−24cm3 and density of element is 7.2 g/cm3. Calculate the number of atoms present in 200 g of the element.

1.	An element crystallises into a structure which may be described by a cubic unit cell having one atom at each corner of the cube and two atoms on one of its diagonals. If the volume of this unit cell is 24×10−24cm3 and density of element is 7.2 g/cm3. Calculate the number of atoms present in 200 g of the element.
Answer» An element crystallises into a structure which may be described by a cubic unit cell having one atom at each corner of the cube and two atoms on one of its diagonals. If the volume of this unit cell is $24 \times 10^{- 24} {cm}^{3}$ and density of element is $7.2 {g/cm}^{3}$ . Calculate the number of atoms present in $200 g$ of the element.
