Chapter 1, Problem 123CP

Sterling silver is a solid solution of silver and copper. If a piece of a sterling silver necklace has a mass of 105.0 g and a volume of 10.12 mL, calculate the mass percent of copper in the piece of necklace. Assume that the volume of silver present plus the volume of copper present equals the total volume. Refer to Table 1.5.

$\text{Mass percent of copper = }\frac{\text{mass of copper}}{\text{total mass}}\times 100$
