A high-protein diet contains 70. g {\rm g} of carbohydrate, 5.0 g {\rm g} of fat. How much energy in kilocalories does this diet provide? round to the nearest tens place
A high-protein diet contains 70. g of carbohydrate, 5.0 g of fat, and 150 g of protein. How much energy, in kilojoules, does this diet provide?
Round off the answer to the tens place.
Fat: 1 gram = 9 calories
Protein: 1 gram = 4 calories
Carbohydrates: 1 gram = 4 calories
What is 70*4+5*9?
325
To calculate the energy provided by the diet, we need to know the energy content per gram of carbohydrate, fat, and protein.
The energy content per gram of carbohydrate and protein is 4 kilocalories (kcal), while fat provides 9 kilocalories per gram.
Given the amount of carbohydrate (70 g) and fat (5.0 g) in the diet, we can calculate the energy they contribute:
Energy from carbohydrate: 70 g × 4 kcal/g = 280 kcal
Energy from fat: 5.0 g × 9 kcal/g = 45 kcal
To find the total energy provided by the diet, we sum up the energy from carbohydrate and fat:
Total energy = Energy from carbohydrate + Energy from fat
Total energy = 280 kcal + 45 kcal = 325 kcal
Therefore, the high-protein diet provides approximately 325 kilocalories.
