Nutrition help...please help!!?

1. Calculate the energy provided by a food鈥檚 energy-nutrient contents. Please show all calculations.

A cup of New England clam chowder contains 6 grams of protein, 18 grams of carbohydrate, and 12 grams of fat.
a. How many kilocalories (kcals) does the chowder provide from these energy nutrients?

____________________ = __________ kcal protein

____________________ = __________ kcal carbohydrate

____________________ = __________ kcal fat

Total = __________ kcal

b. What percentage of the energy in the chowder comes from each of the energy-yielding nutrients?

____________________ = __________ % kcal from protein

____________________ = __________ % kcal from carbohydrate

____________________ = __________ % kcal from fat

Total = __________ %

Note: The total should add up to 100%; 99% or 101% due to rounding is also acceptable.

c. Calculate how many of the 122 kcals provided by a 5 fl. oz. serving of Merlot comes from alcohol, if the wine contains 4 grams of carbohydrate. (Note: The remaining kcals derive from alcohol.)

4 g carbohydrate = __________ kcal carbohydrate

= __________ kcal alcohol

How many grams of alcohol does this represent? __________ g alcohol

Ok well i was able to answer a and b. i attempted to do c but i got a little confused so hopefully somebody else can help you out with that one.

a)
6 g protein * 4 = 24 kcal protein
18 g carbs * 4 = 72 kcal carbs
12 g fat * 9 = 108 kcal fat
Total: 204

* Note:
1 gram protein = 4 kcal
1 gram carb = 4 kcal
1 gram fat = 9 kcal
1 gram alcohol = 7 kcal

b)
24 g protein/204= 11.7% protein
72 g carb/204= 35.2% carb
108 g fat/204= 53% fat
Total: 99.9%

c) ok im gonna attempt this one.

4 g carb = 16 kcal carb
122 kcal - 16 kcal carb = 106 kcal alcohol
106 kcal alcohol/7 = 15 g alcohol

im sorry if it's not right but i tried lol
