SOLVED:How are a solid’s unit cell and crystal structure related?

A unit cell of iron crystal has edge length 288 pm and density 7.86 g.cm-3. Find the number of atoms per unit cell and type of the crystal lattice. - Chemistry | Shaalaa.com

SOLVED: What do you understand by a crystal lattice and the unit cell? In an fec lattice each unit cell has a lattice point at the centre of each face in addition to those at the corners. (i) Write down the position of atoms. (ii) What will be the primitive cell for the space lattice? (iii) How large is the fec cell as compared to the primitive cubic cell? | Numerade
