SIR, I have some question based on the numericals:
1: An element of atomic mass 98.5 g mol–1 occurs in fcc structure. If its unit cell edge length is 500 pm and its density is 5.22 g cm–3. Calculate the value of Avogadro constant.
2: An element crystallises in a cubic close packed structure having a fcc unit cell of an edge 200 pm. Calculate the density if 200 g of this element contains 24 × 10 23 atoms
