.- Niobium forms a substitutional solid solution 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 niobium and vanadium are 8.57 and 6.10 g/cm3, respectively. slader

Number of atoms per per cubic centimeter for a niobium-vanadium alloy:

Explanation:

Suppose in 100 grams of solid sample has 24% of Nb and 76% of V.

Mass of Nb = 24 g

Volume of the Nb = v

Density of Nb =

Mass of V = 76 g

Volume of the V = v'

Density of V =

Volume of the solid alloy = v + v' =

Moles of Nb =

Number of atoms of Nb in 0.2580 mol = N
