Question

An alloy is composed of elements A (85%) and B (15%) by weight. The density of the alloy is 1.88 g/cm^3. The properties of these elements are: Element A----Gross atomic weight = 23.0898 a-barns=0.18 s-barns=1.39 Element B----Gross atomic weight = 24.0065 a-barns=0.22 s-barns=2.50 A) Determine the atom density for the two elements. element A = ? element B = ? B) The absorption cross section for the two elements. element A = ? element B = ? C) The scattering cross section for the two elements. element A = ? element B = ? D) The mean-free path for the absorption for the two elements. element A = ? element B = ? Please show all work.
