A chunk of mercury at 80.8°C was added to 200.0 g of water at 15.5°C. The specific heat of mercury is 0.14 J/gºC, and the specific heat of water is 4.184 J/gºC. When the temperature stabilized, the temperature of the mixture was 20.9°C. Assuming no heat was lost to the surroundings, what was the mass of mercury added? a) 399 g b) 4948 539 g d) 2.08 kg e) 682 g
