Explanation:
The percent of kcal in low-fat chocolate milk that comes from protein
To find the percent of kcal that comes from protein, we need to determine how many kcal come from protein in the 8-ounce glass of milk.
Given that the milk contains 8 grams of protein, we can calculate the total kcal from protein by multiplying the protein grams by 4, as each gram of protein provides 4 kcal of energy. In this case, 8 grams * 4 kcal/gram = 32 kcal.
Next, we can calculate the percent of kcal that comes from protein by dividing the kcal from protein (32 kcal) by the total kcal in the milk (160 kcal) and multiplying by 100. Thus, (32 kcal / 160 kcal) * 100 = 20 percent.
Therefore, 20 percent of the kcal in the low-fat chocolate milk comes from protein.
