When a 7.98 g sample of solid potassium chlorate (KCLO3) dissolves in 60.0 g of water in a coffee-cup calorimeter, the temperature drops from 28.5 to 19.0 °C. Calculate the heat absorbed or released in the dissolution of potassium chlorate, and express your answer in joules or kilojoules. Assume no heat is lost to the surroundings and that the specific heat capacity of water is 4.18 J/g°C.
