At a certain temperature and pressure an element has a simple body-centred cubic unit cell,?

Question

The corresponding atomic radius is 1.566 Å and the density is 6.407 g cm-3. Calculate the atomic mass for this element (in amu).

Answer 1

Determine how many atoms in a single simple body cubic unit...I think there is 2...Now determine the size of the edge of the cube which is 1.566 angstroms...How many cubes fits in a cc....(1cm/1.566 angstroms)^3...multiply by 2...Now you have how many atoms in a cc...divide by Avogadro's number and you have how many moles...6.407/#of moles and that's your answer

Answer 2
