Question: When a Cu-Zn alloy solidifies, one portion of the structure contains 25 atomic percent zinc and another portion 0.025 mm away contains 20 atomic percent

When a Cu-Zn alloy solidifies, one portion of the structure contains 25 atomic percent zinc and another portion 0.025 mm away contains 20 atomic percent zinc. The lattice parameter for the FCC alloy is about 3.63 × 10-8 cm. Determine the concentration gradient in
(a) Atomic percent Zn per cm;
(b) Weight percent Zn per cm; and
(c) Zn atoms/(cm3 · cm).
