A pure gold ring and pure silver ring have a total mass of 15.7 g. The two rings are heated to 65.3 degree celcius and dropped into a 13.3 mL of water at 21.2 degree celcius. When equilibrium is reached, the temperature of the water is 23.3 degree celcius.
What is the mass of gold ring? Assume a density of 0.988 g/mL for water
What is the mass of silver ring? Assume a density of 0.998 g/mL for water
