?A pure gold ring and pure silver ring have a total mass of 14.9 g. We heat the two

Chapter 9, Problem 114

(choose chapter or problem)

A pure gold ring and pure silver ring have a total mass of 14.9 g. We heat the two rings to \(62.0^{\circ} \mathrm{C}\) and drop them into 15.0 mL of water at \(23.5^{\circ} \mathrm{C}\). When equilibrium is reached, the temperature of the water is \(25.0^{\circ} \mathrm{C}\). What is the mass of each ring? (Assume a density of 0.998 g/mL for water.)
