the total Kilojoules for one cup of orange juice that contains 29 g of carbohydrate, no fat, and 1 g of protein Express your answer to two significant figures and include the appropriate units.
Carbohydrates- 17
Fat- 38
Protein-4
The total kilojoules for one cup of orange juice can be calculated using the following equation:
Total kilojoules = (Carbohydrates x 17) + (Fat x 38) + (Protein x 4)
In this case, the values are:
Carbohydrates = 29 g
Fat = 0 g
Protein = 1 g
Plugging in these values into the equation, we get:
Total kilojoules = (29 x 17) + (0 x 38) + (1 x 4)
= 493 + 0 + 4
= 497
Therefore, the total kilojoules for one cup of orange juice is 497 kilojoules.
To calculate the total kilojoules for one cup of orange juice, we need to know the amount of kilojoules per gram for each macronutrient.
Carbohydrates have 17 kilojoules per gram.
Fat has 38 kilojoules per gram.
Protein has 4 kilojoules per gram.
Given that one cup of orange juice contains 29 g of carbohydrates, 0 g of fat, and 1 g of protein, we can calculate the total kilojoules as follows:
Total kilojoules = (29 g of carbohydrates * 17 kilojoules/gram) + (0 g of fat * 38 kilojoules/gram) + (1 g of protein * 4 kilojoules/gram)
Total kilojoules = (493 kilojoules) + (0 kilojoules) + (4 kilojoules)
Total kilojoules = 497 kilojoules
Therefore, the total kilojoules for one cup of orange juice is 497 kilojoules.
To calculate the total kilojoules for one cup of orange juice, we need to determine the energy content from each macronutrient (carbohydrates, fat, and protein) and then add them together.
First, let's calculate the kilojoules from carbohydrates:
Carbohydrates provide approximately 17 kilojoules per gram. Since there are 29 grams of carbohydrates in one cup of orange juice, we can multiply 29 g by 17 kJ/g:
29 g * 17 kJ/g = 493 kJ
Next, let's calculate the kilojoules from fat:
Fat provides approximately 38 kilojoules per gram. However, since there is no fat in the orange juice, the kilojoules from fat will be zero.
Finally, let's calculate the kilojoules from protein:
Protein provides approximately 17 kilojoules per gram. Since there is 1 gram of protein in one cup of orange juice, we can multiply 1 g by 17 kJ/g:
1 g * 17 kJ/g = 17 kJ
Now, we can add the kilojoules from each macronutrient together to find the total:
493 kJ + 0 kJ + 17 kJ = 510 kJ
Therefore, the total kilojoules for one cup of orange juice that contains 29 g of carbohydrates, no fat, and 1 g of protein is 510 kJ.
