A 15-g sample of the candy is placed in a small aluminum container of mass 0.325 kg filled with oxygen. This container is placed in 1.75 kg of water in an aluminum calorimeter cup of mass0.624 kg at an initial temperature of 15.0 ?C. The oxygen-candy mixture in the small container (a "bomb calorimeter") is ignited, and the final temperature of the whole system is 53.5 ?C. The value of specific heat for aluminum is0.22 Cal/kg?C?, and for water is1.00 Cal/kg?C?.
Determine the Calorie content of 69g of candy.
Q= _____cal
