A candy bar has a total mass of 75g. In a calorimetry experiment, a 1.0-g sample of this candy bar was burned in a calorimeter surrounded by 1000g of water. The temp. of the water in contact with the burning candy bar was measured and found to increase from an initial temp. of 21.2 deg. C to a final temp. of 24.3 deg. C

a.) calculate the amount of heat in calories released when the 1.0-g sample burned
b.) convert the heat in calories to nutritional Calories and then calculate the energy content (fuel value) in Cal/g
c.) calculate the total caloric content of the candy bar in Calories
