to calulate the calories(kcal) in 1/2 cup of soft ice cream that contains 16g carbs, 17g fat, 5g protein.

do I multiply
16g x 4 for carbs
17g x 9 for fat
5g x 4 for proteins?
then do I do conversion factors for
grams to 1/2cup? am I on the right road?

I do not think the 1/2 cup has anything to do with this problem. It just happens that your amounts, the 16 g, 17 g, and 5 g fit in the half cup.

I will just have to believe you about kilocal per gram for each type of poison.

sorry, Damon. this is a word problem that is on my homework. I think they want to know the kilocalories on this.

Linda, I answered this problem for you earlier. Don't you check your questions for responses.?

Yes, you are on the right track. To calculate the calories in 1/2 cup of soft ice cream, you need to convert the grams of each macronutrient (carbs, fat, and protein) into calories and then add them together.

To convert the grams of carbs to calories, you multiply the grams by 4. So, in this case, it would be 16g x 4 = 64 calories from carbs.

To convert the grams of fat to calories, you multiply the grams by 9. So, in this case, it would be 17g x 9 = 153 calories from fat.

To convert the grams of protein to calories, you also multiply the grams by 4. So, in this case, it would be 5g x 4 = 20 calories from protein.

Now, you can add up the calories from each macronutrient to calculate the total calories in 1/2 cup of soft ice cream:

64 calories from carbs + 153 calories from fat + 20 calories from protein = 237 calories.

Therefore, there are approximately 237 calories in 1/2 cup of soft ice cream that contains 16g carbs, 17g fat, and 5g protein.

Regarding your question about conversion factors for grams to 1/2 cup, it is not necessary to convert grams to 1/2 cup in this case. The provided information already gives you the nutritional values (carbs, fat, and protein) for 1/2 cup of soft ice cream. So you can directly use those numbers to calculate the calories.
