How many unit cells are there in $$1.00$$ gm cube shaped ideal crystal $$AB (MF = 60)$$ having $$NaCl$$ type lattice?

In a cubic close packing of spheres in three dimensions, the co-ordination number of each sphere?

In a hypothetical solid, C atoms are found to form cubical close-packed lattice . A atoms occupy att tetrahedral voids and B atoms occupy all octahedral voids.
A and B atoms are of appropriate size, so that there is no distortion in the ccp lattice of C atoms .Now if a plane as shown in the following figure is cut, then the cross section of this plane will look like?

The unit cell cube length for $$LiCl$$ (just like $$NaCl$$ structure) is $$5.14 \ \mathring { A } $$. Assuming anion-anion contact, the ionic radius for chloride ion is:

A compound $$CuCl$$ has face centered cubic structure. Its density is $$3.4 \ g \ cm^{-3}$$. The length of unit cell is :

The Aluminium chloride crystallizes in BCC lattice with an edge length of unit cell equal to $$387\ pm $$. If the size of $$Cl^- $$ ion is $$181\ pm $$, the size of $$NH_4^{+} $$ ion would be:
