Red gold is a gold-copper alloy used to make jewelry. A piece of jewelry made of red gold weighs 7.61 g and has a volume of 0.432 cm^3? Gold has a density of 19.3 g/cm² and copper has a density of 8.96 g/cm^3.
Calculate the percentage by mass of each metal in the jewelry. Assume the total volume of the jewelry is the sum of the volumes of the two metals it contains.

Ithink 2 is the correct
