16. The six-cookie serving size contains 1320 calories.
17. When converted to joules (1 cal = 4.184 J), it amounts to 5524.8 Joules, considering there are about 11 servings per container.
16. To determine the energy content in the six-cookie serving size, we start with the provided information. Each serving, consisting of 6 cookies and weighing 28g, contains 120 calories. Given that there are about 11 servings per container, we can calculate the total energy content in the entire package:
![\[ \text{Total energy content (calories)} = \text{Calories per serving} * \text{Number of servings per container} \]](https://img.qammunity.org/2022/formulas/chemistry/college/gg0w2h24ivn8ogf5h8kz0g4n6apzhxu7ti.png)
![\[ \text{Total energy content} = 120 \, \text{calories/serving} * 11 \, \text{servings} = 1320 \, \text{calories} \]](https://img.qammunity.org/2022/formulas/chemistry/college/wn55tinto3m8mf1qims1tw6u6bt8f6zv83.png)
17. Now, to convert calories to joules, we use the conversion factor:
. Additionally, 1 Calorie (with a capital "C") is equivalent to 1 kilocalorie (kcal). Therefore, 1 Calorie = 4184 Joules.
![\[ \text{Total energy content (joules)} = \text{Total energy content (calories)} * 4.184 \, \text{Joules/calorie} \]](https://img.qammunity.org/2022/formulas/chemistry/college/v0rlgwylhk5f31c975gw0pwyeixe6fgtg1.png)
![\[ \text{Total energy content (joules)} = 1320 \, \text{calories} * 4.184 \, \text{Joules/calorie} = 5524.8 \, \text{Joules} \]](https://img.qammunity.org/2022/formulas/chemistry/college/eumh6mt71slug6oe29vzi3uid31ux7xlww.png)
