In the laboratory a student uses a coffee cup calorimeter to determine the specific heat of a metal. She heats 18.5 grams of magnesium to 98.57°C and then drops it into a cup containing 75.7 grams of water at 21.58°C. She measures the final temperature to be 26.02°C. Assuming that all of the heat is transferred to the water, she calculates the specific heat of magnesium to be J/g°C.
