3. In your calculation, you assumed that all the heat released by the combusted food item was absorbed by the water. Do you think this is true or not? If it is not true, would this tend to make your estimated calories too big or too small?
4. The night shift nurse at Northside hospital administers 255 mL of an IV solution of glucose whose concentration is 5.00 % m/V ( 5.00 g glucose in 100 mL solution). Calculate the kilocalories of energy that is provided to this patient. Carbohydrate – 4 kcal/g Fat – 9 kcal/g
Protein – 4 kcal/g
Convert the scientific calories above in Column 1 of Table 2 into food Calories and report this value in Column 2 of Table 2. 1 Cal (food) = 1000 cal (scientific) = 1 kcal (scientific).
