In the laboratory a student uses a "coffee cup" calorimeter to determine the specific heat of a metal. She heats 18.2 grams of magnesium to 97.90°C and then drops it into a cup containing 83.6 grams of water at 21.86°C. She measures the final temperature to be 25.58°C. Assuming that all of the heat is transferred to the water, she calculates the specific heat of magnesium to be J/g °C.
