A particular ring contains both 18 K gold and sterling silver, with the two metals in an intricate design resembling braided ropes. The total mass of the ring is 15.0 g, and a jeweler wants to determine the masses of gold and of silver present. The clever jeweler places the ring into some hot water, heating it to a temperature of 87.6°C, and then drops the hot ring into 18.0 g of water at 21.8°C. When the ring and the water reach thermal equilibrium, the final temperature is 24.0°C. What mass of gold is present in the ring?
Specific heats: 18 K gold: 0.132 J g–1 °C–1 Sterling silver: 0.245 J g–1 °C–1 Water: 4.184 J g–1 °C–1
