the grams of carbohydrate in one apple if the apple has no fat and no protein and provides 51 kcal of energy
Express your answer to two significant figures and include the appropriate units.
To determine the grams of carbohydrates in one apple, we need to know the calorie content per gram of carbohydrates. Carbohydrates have 4 calories per gram.
Given that the apple provides 51 kcal of energy, we can calculate the grams of carbohydrates as follows:
51 kcal ÷ 4 kcal/g = 12.75 g
Therefore, there are approximately 12.75 grams of carbohydrates in one apple.
To find the grams of carbohydrates in one apple, we need to first convert the provided energy from kcal to cal, and then use the conversion factor for carbohydrates.
1 kcal = 1000 cal
So, 51 kcal = 51,000 cal
The conversion factor for carbohydrates is 4 calories per gram.
Therefore, the number of grams of carbohydrates in one apple can be calculated as:
Carbohydrates (g) = Energy (cal) / Conversion factor (cal/g)
Carbohydrates (g) = 51,000 cal / 4 cal/g
Carbohydrates (g) = 12,750 g
However, since we need to express the answer to two significant figures, the result is 13,000 grams.
Therefore, there are approximately 13,000 grams of carbohydrates in one apple.
