Fraction of empty space in ABAB type arrangement in 3D

An element A having molar mass of 100 g mol^(-1) crystallises in AAA....type of packing in 3D with HCP arrangement in each of layer.If the radius of atom is (10)/(sqrt(3))Å then find out the density of the element (N_(A)=6times10^(23) atom/mole)

The spatial arrangement of atoms that characterises a particular stereoisomers is called.

2xx10^(8) atoms of carbon are arranged side by side. Calculate the radius of carbon atom if the length of this arrangement is 2.4 cm .
