A pure gold ring (c = 0.128 J/g°C) and pure silver ring (c = 0.235 J/g°C) have a total mass of 16.907 g. The two rings are heated to 66.881 oC and dropped into a 13.916 mL of water at 21.9 oC. When equilibrium is reached, the temperature of the water is 24.2 oC.
What is the mass of gold ring? (Assume a density of 0.998 g/mL for water.)
