In the laboratory a student uses a "coffee cup" calorimeter to determine the specific heat of a metal. She heats 19.5 grams of tin to 98.62°C and then drops it into a cup containing 78.8 grams of water at 22.92°C. She measures the final temperature to be 23.89°C. Assuming that all of the heat is transferred to the water, she calculates the specific heat of tin to be ---------- J/g°C.
