A 10-g sample of a cookie is allowed to dry before putting it in a bomb calorimeter. The aluminum bomb has a mass of 0.615 kg and is placed in 2.00 kg of water contained in an aluminum calorimeter cup of mass 0.524 kg . The initial temperature of the system is 15.0°C , and its temperature after ignition is 36.0°C . The value of specific heat for aluminum is 0.22 kcal/kg⋅C° , and for water is 1.00 kcal/kg⋅C° .
(a) Determine the energy content of 100g of cookies in kcal.
