Use the equation q=Q&bull;&Delta;T/m,
where q-heat of compound, Q - heat capacity of the calorimeter, &Delta;T &ndash; change the temperature, m &ndash; mass of compound.
q=32.4&bull;2.56/3.4=24.395 kJ/g=5.831 kcal/g=5831 cal/g.

Answer: The quantity of nutritional Calories per gram of the candy is 5831.
