Copper crystallizes in a face-centered cubic cell. Copper's density is 8.92 g?cm3, and its molar mass is 63.55 g/mol. Determine the radius (in pm) of a copper atom.
Sterling silver is a solid solution of silver and copper. If a piece of a sterling silver necklace has a mass of 160.0 g and a volume of 15.42 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. (Density of Cu = 8.96 g/cm^3: density of Ag = 10.5 g/cm.) mass percent of copper = mass of copper/total mass times...
