1. Molybdenum forms a substitutional solid solution with tungsten. Compute the number of molybdenum atoms per cubic centimeter for a molybdenum-tungsten alloy that contains 16.4 wt% Mo and 83.6 wt% W. The densities of pure molybdenum and tungsten are 10.22 and 19.30 g/cm3, respectively.

2. Niobium forms a substitutional solid solu- tion with vanadium. Compute the number of niobium atoms per cubic centimeter for a niobium-vanadium alloy that contains 24 wt% Nb and 76 wt% V. The densities of pure pure Ge and Si are 5.32 and 2.33 g/cm3, respectively.

3. Iron and vanadium both have the BCC crys- tal structure, and V forms a substitutional solid solution for concentrations up to ap- proximately 20 wt% V at room temperature. Compute the unit  cell  edge  length  for  a 90 wt% Fe-10 wt% V alloy.
