A hypothetical metal has the simple cubic crystal structure shown in the Figure below. If its atomic weight is 79.1 g/mol and the atomic radius is 0.131 nm, compute its density.    

Sketch the BCC structure and     a) Calculate the atomic packing factor.     b) Mark the (110) plane in the BCC structure and show/sketch how the atoms are arranged in the (110) plane.     c) Using the sketch in b, derive the relationship between a and R.     d) Calculate the linear density of the [111] direction.
