I am struck with these Questions, can anyone help me pls..
1)Nickel has a face-centered cubic unit cell with the edge of this unit cell of length 352.4 pm. Whats the density of nickel in g.cm-3??
2) The radius of S2- ion as 184pm and the density of Zincblende as 4.60 g.cm-1, calulate a value for Avogadro's number. (Assume that sulphide ions touch along the cell diagonal).
Thanks for the help. Highly appreciate Zain
