A 83.5 g sample of a metal alloy is heated to 88.1oC and it is then placed in a coffee-cup calorimeter containing 30.0 g water at 15.0oC. The final temperature of the metal + water is 25.3 oC. Calculate the specific heat of metal alloy, in J/(g oC), assuming no heat escapes to the surroundings or is transferred to the calorimeter. The specific heat of water is 4.184 J/(g oC).
