Question

While working on his diet log, Charles observed that the Nutrition Facts label for Snack Crackers states that one serving contains 19 g of carbohydrate, 4 g of fat, and 2 g of protein. If Charles eats one serving of Snack Crackers, what is the energy, in kilocalories, from each food type and the total kilocalories? Round off the kilocalories for each food type to the tens place.

Accepted Answer

STEP 1 State the given and needed quantities.

ANALYZE THE PROBLEM	Given	Need	Connect
ANALYZE THE PROBLEM	19 g of carbohydrate, 4 g of fat, 2 g of protein	total number of kilocalories	energy values

STEP 2 Use the energy value for each food type to calculate the kilocalories, rounded off to the tens place.

Food Type	Mass Energy Value Energy
Carbohydrate	[latex] 19 \cancel{g} imes \frac{4 kcal}{1 \cancel{g}} = 80 kcal [/latex]
Fat	[latex] 4 \cancel{g} imes \frac{9 kcal}{1 \cancel{g}} = 40 kcal [/latex]
Protein	[latex] 2 \cancel{g} imes \frac{4 kcal}{1 \cancel{g}} = 10 kcal [/latex]

STEP 3 Add the energy for each food type to give the total energy from the food.

Total energy = 80 kcal + 40 kcal + 10 kcal = 130 kcaL
