    - After burning: 0.05g
    -Temp. increase of 200g of water: 7.0 degrees Celsius

    1. Calculate the total energy released by the combustion of the cashew nut by using the water temp. increase, the mass of the water and specific heat capacity of water.

    2.Calculate the energy released per gram of cashew nut consumed in the reaction.

    3. Using the following standards ( Carbohydrates (4 Cal/g), protein (4Cal/g), and fats 9 Cal/g), determine the caloric content of a bag of your favorite snack food. ( use pretzels)
