Problem: A pure gold ring and pure silver ring have a total mass of 16.0 g. The two rings are heated to 71.1 oC and dropped into a 13.6 mL of water at 21.8 oC. When equilibrium is reached, the temperature of the water is 24.2 oC. What is the mass of silver ring? (Assume a density of 0.998 g/mL for water.)
