A 2.59 g sample of a substance suspected of being pure gold (Cs = 0.128 J g−1°C−1) is warmed to 81.3 °C and submerged into 14.8 g of water initially at 24.0 °C. The final temperature of the water and the gold is 26.9 °C. Assume that the specific heat capacity of water is 4.18 J g−1°C−1.What is the heat capacity of the unknown substance? Express your answer to 3 significant figures.
