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).
How much heat (in Joules) was absorbed by the water in
the calorimeter?_________ (Write your answer
in 2 decimal places without
the unit).
