Q3 Two metals with a BCC crystal structure (V and Fe) form a substitutional solid solution for all concentrations at room temperature. Determine the unit cell edge length for a

45 wt.% Fe, 55 wt.% V alloy. The density at room-temperature and the atomic weight are 7.87 g/cm³ and 55.85 g/mol (Fe), and 6.10 g/cm³ and 50.94 g/mol, for Vanadium respectively. a) What is the average density of this solid solution? (2 marks) b) What is the average atomic weight? (2 marks) c) What is the volume of the unit cell in cm³? (2 marks) d) What is the unit cell dimension in cm? (2 marks)
