A coffee-cup calorimeter contains 70 mL of water with an initial temperature of 24.9°C. An unknown sample with a mass of 6.259 grams was placed inside making the water temperature rise up to 25.5°C. The initial temperature of the metal was 86.4°C. (Water: density = 1g/mL; specific heat = 4.184 J/g-°C). 1. How much heat (in Joules) was absorbed by the water in the calorimeter?_________ (Write your answer in 2 decimal places without the unit).
