Materials Science and Engineering: An Introduction
Gold forms a substitutional solid solution with silver. Compute the weight percent of gold that must be added to silver to yield an alloy that contains $5.5 \times 10^{21}$ Au atoms per cubic centimeter. The densities of pure Au and $\mathrm{Ag}$ are 19.32 and $10.49 \mathrm{g} / \mathrm{cm}^{3},$ respectively.
