Question

silver crystallises in cubic lattice with a density of 10.5g per cc and Edge length 0.41nm. suggest the type of crystal
​

Answer 1

Answer:

Here,Density=10.5×10^4 kg/m^3

Volume={0.41×10^(-12)}^3

Molecular Mass=107.87

Avagrado's No.=6.022×10^23

Rank=Density×Volume×Avagrado's No./Molecular Mass

Rank=10.5×10^4×{0.41×10^(-12)}^3×6.022×10^23/107.87

Rank=4

The type of crystal is Face-Centred Cublic Lattice
