Assistance A serving of Grape-Nuts cereal (8.77 g) is burned in a bomb calorimeter with a heat capacity of 38.79 kJrC. During the combustion, the temperature of the water in the calorimeter increased by 3.93 C. Calculate the energy content (in kJ g) of Grape-Nats. energy content per gram - View Hint kJg Gulded Solution

Explanation / Answer

m = 8.77

C = 38.79 kJ/C

dT = 3.93

then

Q = C*dT = 3.93*38.79 = 152.4447 kJ

then

Hcontent = Q/m = 152.4447/(8.77) = 17.38251 kJ/g
