To determine

To calculate: Calories in potato chips.

Answer to Problem 23.1APP

Total amount of calories in a $100\text{ g}$ potato chips is $\underset{\_}{555}$ .

Explanation of Solution

Given:

Calories supplied by fats = $9\text{ calories/gram}$

Calories supplied by carbohydrates = $\text{4 calories/gram}$

Calories supplied by proteins = $\text{4 calories/gram}$

Amount of potato chips = $100\text{ g}$

Amount of protein = $7\text{ g}$

Amount of carbohydrate = $\text{53 g}$

Amount of fat = $\text{35 g}$

Calculation:

Calories supplied by $\text{1 g}$ of fats = $9$

Calories supplied by $\text{35 g}$ of fats = $9\times 35=315$

Calories supplied by $\text{1 g}$ of carbohydrate = $4$

Calories supplied by $\text{53 g}$ of fats = $4\times 53=212$

Calories supplied by $\text{1 g}$ of protein = $4$

Calories supplied by $\text{7 g}$ of carbohydrate = $4\times 7=28$

Therefore, total amount of calories in a $100\text{ g}$ potato chips = $315+212+28=555$

Conclusion:

Total amount of calories in a $100\text{ g}$ potato chips is $\underset{\_}{555}$ .
