A student is using a calorimeter to determine the specific heat of a metallic sample. She measures out 128.1 grams of her metal and heats it to 79.6 degrees Celsius. Then, she puts the sample into a calorimeter containing 11.47 grams of water at 45.7 degrees Celsius. She measures the temperature of the water in the calorimeter until the number stops changing, then records the final temperature to be 71.4 degrees Celsius. What is the specific heat of the metal? Please answer to three digits after the decimal point.
