Red gold is a gold-copper alloy used to make jewelry. A piece of jewelry made of red gold weighs 8.50 g and has a volume
of 0.583 cm. Gold has a density of 19.3 g/cm³ and copper has a density of 8.96 g/cm³. 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.
