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.

college chemistry
Yes, on the right track. The 16 x 4 will give kcal for carbs. The 17 x 9 will give kcal for fat. The 5 x 4 will give kcal for proteins. Then add all of them together for total kcal. You don't need to factor in the 1/2 cup because the problem tells you the grams of protein...

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?
