Together, a pure gold ring and a pure titanium ring have a mass of 16.00 g. both rings are heated to 80.0 °c and dropped into 14.1 ml of water at 22.6 °c. the water and the rings reach thermal equilibrium at a temperature of 28.0 °c. the density of water is 0.998 g/ml. the specific heat capacity of water is 4.18 jg·°c, the specific heat capacity of gold is 0.129 jg·°c, and the specific heat capacity of titanium is 0.544 jg·°c. calculate the mass of each ring.
