Sterling silver is a solid solution of silver and copper. If a piece of a sterling silver necklace has a mass of 130.0 g and a volume of 12.53 ml, calculate the mass percent of copper in the piece of nocklace. Assume that the volume of silver present plus the volume of copper present equals the total volume. (Density of Cu-896 g/cm'; density of Ag-105 t/cm') Mass percent of copper mass of copper x 100 total mass Mass percent of copper

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
