Niobium forms a substitution solid solution with vanadium. Compute the number of niobium atoms per cubic centimetre for a niobium–vanadium alloy that contains 27 wt% Nb and 73 wt% V. The densities of pure niobium and vanadium are 8.57 and 6.10 g/cm3, respectively. Also, the atomic weights for niobium and vanadium are 92.91 and 50.94 g/mol, respectively.
Consider a hypothetical metal that has a hexagonal close-packed crystal structure and an atomic weight of 70.28 g/mol. If the atomic radius is 0.1473 nm and the c/a ratio is 1.723, then calculate (a) the unit cell volume, and (b) the density of the m..
