Iron and vanadium both have the BCC crystal structure and V forms a substitutional solid solution for concentrations up to approximately 20wt%V at room temperature. An X-ray diffraction experiment was performed on an ironvanadium alloy using CuKa(=0.1542nm) and the first recorded diffraction peak (lowest hkl) was found at 44.502(2). What is the vanadium concentration of this alloy in weight percent? State any assumptions you made
