Here's an example of how to use nutritional data to determine the % fat, carb and protein in a food. Let's say that you included 33 grams of egg whites, 33 grams of sugar and 11 grams of flour in an angel food cake with a total mass of 77 grams. In-order-to determine the % fat, carbohydrates and protein in the angel food cake, here's what you need to do Go to the website and search for 'egg whites'. The nutritional label tells you that in a 243 gram serving size of egg whites, there are 26 grams of protein and 2 grams of sugar and 0 grams of fat. Use the nutritional data and the mass of egg whites which you used in the cake to find the mass of proteins and sugars in your cookies from egg whites Mass of protein in egg whites = Total mass of serving size Mass of protein from egg whites in cake Mass of egg whites you used in cake From the nutritional OR 26 /243 = x/33 and x = 3.53 grams of protein from egg whites Mass of carbs in egg whites Total mass of serving size Mass of carbs from sugar in cake Mass of egg whites used in cake OR 2/243 = .008 grams of carbs from egg whites Do likewise for the other ingredients in the angel food cake To find the 96 carbs in the cake, add together all-of the grams of carbs from each of the angel food cake ingredients, then divide by the total mass of the angel food cake. Finally, multiply by 100 to convert to a percentage Follow the same steps to find the % protein and the % fat in the cake . · SHOW YOUR WORK AND CALCULATIONS FOR PARTIAL CREDIT % Protein in Your Own Cookie % Carbohydrates in Your Own Cookie % Fat in Your Own Cookie

Explanation / Answer

Given,

Total mass of angel food cake = 85 grams

Mass of egg whites = 35 grams

Mass of sugar = 31 grams

Mass of flour = 19 grams

From the nutritional labels

(1) 243 grams of egg whites contain 26.5 grams of protein, 1.8 grams of carbohydrates and 0 grams of fat

(2) 120 grams of sugar contains 0 grams of protein, 120 grams of carbohydrates and 0 grams of fat

(3) 125 grams of flour contains 2.4 grams of protein, 42.5 grams of carbohydrates and 13.8 grams of fat

(a) % Protein in the angel food cake

# Mass of protein in egg whites/Total mass of serving size = Mass of protein from the egg whites in cake/Mass of egg whites you used in cake

=> 26.5/243 = x/35 => x = 26.5*35/243 = 3.82 grams of protein from egg whites

# Mass of protein in sugar = 0 gram

# Mass of protein in flour/ Mass of protein in serving size = Mass of protein from the flour in cake/Mass of flour you used in cake

=> 2.4/125 = x/19 => x = 2.4*19/125 = 0.36 grams of protein from flour

Total amount of protein in the cake = protein from egg whites + protein from sugar + protein from flour

Total amount of protein in the cake = 3.82 + 0 + 0.36= 4.18 grams

% Protein in the angel food cake = (Total amount of protein in the cake/Total mass of angel food cake)*100

% Protein in the angel food cake = (4.18/85)*100 = 4.92%

Hence, % Protein in the angel food cake is 4.92%

(b) % Carbohydrates in the angel food cake

# Mass of Carbohydrates in egg whites/Total mass of serving size = Mass of Carbohydrates from the egg whites in cake/Mass of egg whites you used in cake

=> 1.8/243 = x/35 => x = 1.8*35/243 = 0.26 grams of carbohydrates from egg whites

# Mass of Carbohydrates in sugar/Total mass of serving size = Mass of Carbohydrates from the sugar in cake/Mass of sugar you used in cake

=> 120/120 = x/31 => x = 31 grams of carbohydrates from sugar

# Mass of carbohydrates in flour/ Mass of carbohydrates in serving size = Mass of carbohydrates from the flour in cake/Mass of flour you used in cake

=> 42.5/125 = x/19 => x = 42.5*19/125 = 6.46 grams of carbohydrates from flour

Total amount of carbohydrates in the cake = carbohydrates from egg whites + carbohydrates from sugar + carbohydrates from flour

Total amount of carbohydrates in the cake = 0.26 + 31 + 6.46 = 37.72 grams

% Carbohydrates in the angel food cake = (Total amount of carbohydrates in the cake/Total mass of angel food cake)*100

% Carbohydrates in the angel food cake = (37.72/85)*100 = 44.38%

Hence, % Carbohydrates in the angel food cake is 44.38%

(c) % Fat in the angel food cake

# Mass of fat in egg whites = 0 gram

# Mass of fat in sugar = 0 gram

# Mass of fat in flour/ Mass of fat in serving size = Mass of fat from the flour in cake/Mass of flour you used in cake

=> 13.8/125 = x/19 => x = 13.8*19/125 = 2.10 grams of fat from flour

Total amount of fat in the cake = fat from egg whites + fat from sugar + fat from flour

Total amount of fat in the cake = 0 + 0 + 2.10 = 2.10 grams

% fat in the angel food cake = (Total amount of fat in the cake/Total mass of angel food cake)*100

% fat in the angel food cake = (2.10/85)*100 = 2.47%

Hence, % fat in the angel food cake is 2.47%
