A pure gold ring and pure silver ring have a total mass of 15.9 g . The two rings are heated to 67.7 ∘C and dropped into a 12.4 mL of water at 20.4 ∘C. When equilibrium is reached, the temperature of the water is 22.8 ∘C. Express your answer to two significant figures and include the appropriate units. What is the mass of silver ring? (Assume a density of 0.998 g/mL for water.)
