A 0.200-kg mаss оf metаl with а specific heat оf 1255.8 J/kg·°C, initially at 90°C, is placed in a 0.500-kg calоrimeter, with a specific heat of 418.6 J/kg·°C, initially at 20oC. The calorimeter is filled with 0.100 kg of water, initially at 20°C. The specific heat of water is 4186 J/kg·°C. What is the final temperature once the combination of metal, calorimeter, and water reach equilibrium?
