Calorimetry: an 80-G Aluminum Calorimeter Contains 380 G of Water

Calorimetry: An 80-g aluminum calorimeter contains 380 g of water at an equilibrium temperature of A piece of metal, initially at is added to the calorimeter. The final temperature at equilibrium is 32°C. Assume there is no external heat exchange. The specific heats of aluminum and water are 910 J/kg · K and 4190 J/kg · K, respectively. The specific heat of the metal is closest to

A) 520 J/kg ∙ K.
B) 480 J/kg ∙ K.
C) 390 J/kg ∙ K.
D) 350 J/kg ∙ K.
E) 560 J/kg ∙ K.
