Question 8 (1 point) Vanadium (50.9 g/mol) is a metal that under normal conditions crystallizes in a body- centered cubic lattice and has a density -6 g/cm3. If instead vanadium were to crystallize in a simple cubic lattice, calculate the new density. The atomic radius of vanadium is 205 pm. HINT: First, calculate the edge length of a simple cubic cell from the atomic radius (1 suggest converting to cm at this step). Second, calculate the volume of the unit...
